GOT IT!!!! Had the heater on, tried to pull the wire off the pressure switch and while I was wiggling it, the heater started. My heater is a Raypak, so not sure if it makes a difference, but if the pressure switch is not connected or working properly, jumping the wires will not turn the main burners on. Your video was a huge help. Thank you soooo much!

great video! I moved into a house 9 years ago with this old H200 Heater that was put in back in 2000. 22 years later, still running! In the past 9 years Ive lived here, I have had to do alot of diagnosing myself (every year I start it up I cross my fingers) As you pointed out - These millivolt heaters are pretty basic. If you get to know your system, checking wires for continuity, cleaning contacts can solve alot of issues. I have gone through a few thermopiles, and a pressure switch (replaced prior to seeing your video) I have gone through and replaced limit switches and the on/off switch (because they are easy and cheap) Just waiting for the heat exchanger to blow before I replace the whole thing...at that point, cost wouldnt make sense IMO. Thanks again for they great video on diagnosing and testing!

Why might that be? - It randomly turned on for 5 minutes after trying to jump again, but the second I barely touch the thermostat control knob, it shuts right down! It makes a loud whistling noise the entire time it’s running.

Awesome video. Pilot lights on and all the switches and sensors have 410 milivolts. When I jumper the valve it lights. The black wire that comes down from the thermostat has 410 milivolts. But when I plug it back into the valve and measure the voltage at contact it only measure 11 milivolts on the connector and the contact on the TH side. With everything hooked up I can jumper the valve and it will light as stay lit as long as the thermostat is turned up. When I turn the thermostat down it goes off like it’s suppose to. But it will not relight if I turn the thermostat up again, it had to be jumpered. So not sure what’s cause the voltage to drop once it connected to the the TH terminal. I did put on a new connector on the black wire and sanded down the contact. Anyways any help would be appreciated. Thanks.

Hmm strange, the only thing that would possibly come to mind is depending on the model and capacity of the heater, and the size of the pool, if the temperature goes below a certain point the heater may not be able to bring the water up to temp fast enough and it could go below freezing damaging the heater. Lots of variables but "could" happen I guess. Most people do not have their pools running in those temperatures though.

Hey, yes they are all the same if it a millivolt system then it will be like I showed in the video, if not its probably electric which means it's even easier to repair. Millivolt means the pilot light burns up against a small metal thing that generates power to run the system, like I explained.. if its electric there will be a transformer that takes power form a line somewhere. Not sure what you mean by the spa blower... shoot a video and I can take a look at it. If you are not comfortable with gas and electricity dont touch it cause you can blow yourself up with this stuff. make sure the gas and power is off before going at it. Should you call a repair man make sure they are locally certified and accredited. If you have to pay, might as well pay a professional

Seth Postma Holy crap, sounds like you are not having good luck with your unit. If your pilot flame is out of control there is defiantly a problem in the gas valve, I don't think there is a way to adjust the pilot flame on these units, it's usually set at the factory look up the model of your manifold/controller (usually Honeywell or RobertShaw) and see if there is a screw or something to adjust the pilot flame. Do be very careful especially if you attempt to re-light the flame because the duty of the pilot gas tube is to control the flame, if there is a problem and its letting out to much gas you risk blowing your self up, same reason why you NEVER attempt to re light a burner with the knob on the ON or RUN position. It should always be lit on PILOT as the gas is controlled. You will most likely need to change out the controller valve.

Todd Stephenson Hey, yes most likely the thermopile/thermocoupler is bad or causing some kind of problem (there is actually only one in these units) Firstly make sure you are holding the knob down long enough on PILOT before turning it to the ON position, try holding the knob on pilot for at least 30 seconds to full minute before turning the knob to the ON position. It could also be that the thermo has been knocked off a bit and is not in the right position in the flame. 479Mv is a very good voltage, so I think maybe you are just not holding the knob on pilot long enough to generate enough current for the valve to stay open You can unscrew the thermocouple assembly from the controller and test it for an extended period of time, just be careful screwing and unscrewing it cause the threads are aluminium and if you cross thread them, its not going to be fun. It could also be the controller (main gas valve) has some kind of problem, but I doubt it.

Todd Stephenson Yeah in that case I say try replacing the thermo, shouldn't be hard to track down a part number from Hayward or RobertShaw/Honeywell. Check and see which control valve ("Gas manifold") you have, (If you have a H series similar to this one its most likely made by either RobertShaw or Honeywell) If you buy Hayward's part number (Hayward HAXPLT1931) it's probably going to cost you 5x times as much, and I believe you have to buy the entire assembly with the bracket, spark igniter and pilot tube. These control valves/gas manifolds are very similar between the equipment they are installed in (Hot water tanks, pool heaters, gas fire places, etc...) So you should be able to narrow down a generic part number for the the actual manufactures part and it wont be that expensive. If you cant narrow down the exact part just try to search for "millivolt thermopile" and find one that looks about the same size and has the same range of voltage rating. (Also I made a mistake, these thermopiles do not screw in to the controller with an aluminium tube, the simply screw on to the terminals with wires.)

My heater is not millivolt it is electric and I use propane not natural gas... it has 1 light to show the unit is getting power (which should be constantly on...) and another light that lights up when the unit is running. My heater is definitely getting power from the circuit as I have confirmed it, but for some reason the unit is not getting power all the time. It seems to work some days and not other days. The lights are dark and then I can't light it and then randomly...the next day two later it will have lights and work fine. Sometimes it will even be fine in the morning and light up and then while it is running it will shut off and then I can't get it going again because it has no power. Any ideas? What to check? what could be so intermittent. No wires seem loose in any way either. THANK YOU for the help.

Hi there, I have seen those but never worked on them personally, when you see that it seems to be off, check it and test to make sure if it is getting power, then check the low voltage side of the transformer that is giving power to the gas valve. Most likely a bad power supply. Basically it takes 220 or 110 from your main circuit and then drops it to something lower like 12 or 24v possibly DC, so check the power supply and confirm it is putting out the correct voltage.

Thank you so much for the response. I am pretty I have a bad transformer after putting the multimeter on the case...I will order that part and install. The symptoms have changed a little: Now the heater shows it is getting power and has a light on, but then when I go to start it and the heater clicks and then loses power. So I think the transformer is not giving enough power to ignite the spark. thanks again

Hi. Thanks for the video. I have to jump the th terminals in order to light the main burner, does this mean my thermostat is bad? Thanks

Frank Maduri Could be, remove the the two connectors from the switch on your thermostat, turn the knob until you hear it click, and test with a multi-meter like I did, also if you don't have a multi-meter that measures continuity you can simply use a small battery and and small light bulb to make a simple test circuit broken by the switch you are testing. Never leave your heater unsupervised when it is operating with the terminals jumped, because all safety switches are bypassed.

Hey there... great video. I got mine started by using your jumping method. right when I remove the jumper it turns off. I installed a new pressure switch(the whole unit is new) but still the same thing. Right now the only way I can heat my pool is to leave the jumper inline to have it run. Any ideas?

thanks Chuck P! I already have the new one installed but the only way the unit will run is with the jumper on the millivolt as shown in the video. problem is not with the pressure switch as I did connect the 2 wires but it doesnt fire up unless I jumper the millivolt shown at 13;32 of the video.. any clue what else the problem could be?? have checked all things in the front panel and can't figure it out. Once it's running with the jumper for 30 mins and I remove the wire it stays going?? Problem is that I need to open the panel jumper the wires to get it going for half an hour then remove the jumper and put the panel back on... it's a pain but better than replacing the thing right now for sure.

I just replaced a broken bypass last week, but now the heater won't start up. When I turn on the heater, the gas will come on for 2-3 seconds and then immediately shutoff; any idea what could be causing this? I was thinking it might be the switch from your video, I may have been rough with it when disconnecting the leads. Everything but the bypass was working fine, and I had no issues with ignition before replacing it.
@QuaabQueb

Could be low pressure not causing the switch to fully click, or could be the switch went bad as you say. Do note you dont "need" a bypass unless you are exceeding the flow rate or pressure specified by the manufacturer. Take a multi-meter, set to continuity setting, and attach it to the leads of the switch, see if it makes contact when the pump is on. Alternatively if you do not have a multi-meter on hand you can use a small battery and a light to make a little test circuit.

I am fighting this heater right now. It works intermittently on then off. If I leave the circuit in tact the heater typically will not light under normal circumstances. If I jump the terminals it will start and sometimes remain running when I remove the jumper demonstrating that the circuit is closed. I can then pull and replace all the terminals to each switch and the heater will drop out and ignite as each lead is removed and reconnected. But when I leave it unattended for a period of time it will shut down. Also note. If I press down on the terminals on the gas valve the pilot will disengage. I feel like the gas valve is the issue with some type of a short or poor ground. Do you know if the terminals on the gas valve fail intermittently as I described? Thanks

ron123 The thermostat temperature is not exact, if you have it set really high it may never go off because your pool it to big and simply cannot get as hot as the max temperature on the thermostat. But if the thermostat is not turning the heater off at all, there is a problem with that component and you will need to repair or replace it, see my latest video where I change mine and show how it is done.

I recently had a problem with my manifold gasket leaking and putting out my flame. I had that repaired and then replaced an electronic igniter (H250) I can now hear the igniter click but am not getting any propane flow. No propane smell. All gas supply valves are open. Could this be the pressure switch or is it more of a valve problem?
@QuaabQueb

I am not familiar with the electric ignition models, but generally all gas fired appliances work similarly. Does it have a pilot light? If so can you verify it is lit. If not you should hear the gas hissing through the manifold or regulator very slightly when it tries to ignite. No gas flow at all would indicate a problem with the gas valve.

For wires you can use any wire that is the same size, just cut it then same length then use the crimp connector plugs. The switch is just a regular limit switch, but like I said it is riveted to the assembly with the diaphragm that activates it YOU DO NOT need to replace the entire diaphragm assembly, just grind off the rivets and replace the switch
