This is a weird one, but make sure all the wire connections are in the correct place. I accidentally miss wired a heater like this and it did the same thing.

SOURCE: groen tilt skillet 750 mv control

you need to check the generator in series with flame present. remove one wire from gas valve.put 1 of your meter probes under gas valve terminal where you removed one lead from powerpyle generator.put generator on other probe anything over 600 mv and your generators is ok under replace

SOURCE: i have a hydrotherm boiler with a millivolt gas

Make sure your thermostat can be used with a millivolt system.Most thermostats are for 24 volt systems and don't work for millivolt systems. Also your thermostat wiring cannot be too long and it also needs to be the correct gauge. Normally the thermostat wire size should be 18 AWG up to 50 feet in distance. Also all your wiring connection have to be clean and tight(solid connections). If your connections are the slightest bit loose your millivolts will drop.

Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

Hi,

I am nearly 100% certain that your fireplace has the millivolt gas valve....

If it does not have a power cord going to it then I am sure it is millivolt...

Pilot light won't stay lit after releasing when lighting gas fryer


This symptom indicates something wrong with the millivolt system. Start by checking the wires from the thermopile to the gas valve, insuring they are all tight and in place. Check the hi limit thermostat, if you have an ohm meter it should read .1 or .2 across it. With you meter set to dc millivolts, and flame present on the pilot, read across the thermocouple wires (red and white) to see the millivolts generated, with the thermostat off and the gas valve in pilot position you should get approx 600 millivolt plus minus 50. The pilot will have to be on for a minute or so to get maximum millivolts. If the millivolts are correct, hi-limit closed, and all wiring is connected, you likely have a faulty gas valve. If the hi limit reads more than .1 or .2 replace the limit, if you are not getting the millivolts from the thermopile, replace it.

How to test thermopile on Imperial IFS-40 deep fryer


Hi there.
You will be needing a dc voltmeter set at millivolt to test a thermopile.
measure the voltage across the termials of the thermopile when it is heated by the pilot flame, you should have 600 to 750 millivolt reading.
If the reading is less than 600, try cleaning it with non metal scrubbing pad and/ or try increaing the pilot flame or you have to replace it with a new one.
Try the same with your other fryers with thermopile.
You will be able to find parts at http://www.imperialrange.com
Regards.

What is the problem when millivolt gas valve can not keep it pilot on?


Hi there.
Probably the thermopile is not receiving enough heat from the pilot flame to generate 500 to 750 millivolt to hold pilot flame. The thermopile may have soot or dirt on it so try to clean or the pilot flame itself does not give enough heat, try adjusting pilot flame. Or the thermopile could not generate the right amount of millivolt even if it is clean and receiving enough heat from pilot flame, so better replace the thermopile.
Check also the hi limit, it must have continuity across its terminal.

Hello i have a J5 lincat fryer and the pilot stays alight but the burners won't connect (light) have replaced the thermostat and the thermo couple but still no joy any ideas on this not sure what to do...


Check if there is 500 to 750 millivolts across the thermopile wires; thermopile generates 500 to 750 millivolts if properly heated to energize pilot and main valve solenoids of the gas valve for pilot and main burner operation. If the voltage across the thermopile is good and all wiring connections are ok, I think you have to replace the gas valve.
Regards.

Poilt is very week and will not open gas valve


The reason the control valve is opening slowly is the the Thermopile needs to be replaced. The Thermopile generates millivolts of electricity from the heat of the pilot flame, which then opens the gas valve when heat is called for. Also, check the pilot flame to make sure it's engulfing the thermopile. If it's not the pilot needs to be cleaned.

I have a raypac RP2100 model # CR185MN ASME. I want to know how many millivolts are required to operate the gas valve ?


Generally, it should operate properly at around 500mv. There are different gas valves that require anywhere from 250mv all the way up to 750mv. If you're in that range, the gas valve should work. If you have a weak thermopile, a replacement should do the trick. It's also good to clean all the contacts on the gas valve, pressure switch, and other components. Also make sure you have adequate gas pressure and a strong pilot.

Pilot on logs won't stay lit


Hold pilot button longer. if this doesn't work your Thermopile has gone bad and will not generate enough Millivolts to keep gas valve pilot open. A new thermopile will generate 750 millivolts. It cost less than $20 dollars but is difficult to replace. You should call a certified technician. They will charge you about $100.00

You must first check to see if your pilot flame is good. If it is too weak, or not impinging properly on the thermopile, it will not stay lit. If the pilot flame is ok, the problem could be that the thermopile is weak. using a millivolt meter, test the voltage across the thermopile while the pilot is lit (you may need someone to hold the button down while you do this). You will also need to disconnect the thermopile's leads from the control while you do this. You should get about 750 millivolts across the thermopile while the flame is on it (let it heat for a while to stabilize). If your reading is too low, your thermopile may be shot and needs to be replaced. That is of course only if your flame is proper. That voltage is needed (or close) to keep the magnet open so it will stay lit when you let the button go.
