    Does your pilot sensor feed into the main gas valve or into a motherboard?

If thermopile generates 700mv...the stat is ok and no open limit then it is bad valve...touch the 2 thermopile leads direct t TH and PP on valve to bypass limit and stat...if it works direct...then a limit or stat is open

I changed the thermo coupler and the pilot light does stay lit but the burners won't light


If you are referring to a gas fireplace:

  • Make sure the pilot knob is turned from "pilot" to "ON" or it will never run.
  • If the pilot knob is "ON", and the pilot is lit, but the burner won't light, it could be a bad Thermopile. The thermopile is the other safety mechanism in the pilot assembly that controls the burner.

Pilot light wont stay lighted


Hi there.
Try cleaning the thermopile (cylindrical piece of metal behind the pilot) wwith a non-metal scrubbing pad. thermopile needs the heat of pilot flame to keep the pilot flame lighted as well as burners during operation.
Kindly check also if the gas has sufficient pressure.
Regards.

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.

My fryer model SRTG LIGHT THE PILOT BUT WON'T LIGHT THE MAIN BURNER


check if the thermopile (cylindrical metal standing behind pilot assembly) receives enough heat from pilot flame. if it does, you need to replace the thermopile.

Our LP Buck Stove will suddenly not lite. The pilot is lit. To start the stove, we just push the ON button and the fire lights, it stopped lighting without warning yesterday. Any ideas what is wrong? I...


If I understand it correctly, the pilot light will light and burn, but when you turn the Control Knob to the ON position either the burner won't light? My question is, doe the pilot stay lit or does it go out, when you do this.Also, is this a Vented or Vent-free Gas log Stove?

If it's vent-free, the Oxygen Depletion Sensor (ODS) which is part of the Pilot needs cleaning. As, it may be clogged with dust, lint & pet hair and it's sensing that there is not enough oxygen for safe combustion. The other issue tis relative to the pilot assembly, is whether this unit has a millivolt control valve and the Thermopile has failed. The Thermopile controls the opening and closing of the gas valve when you turn the Control Knob or ON/OFF switch to the ON position.

If it's a Vented unit, the same thing applies to the Thermopile.

It would also be wise to check the amount of gas you have in your tank. It may be to low to sustain combustion of the burner(s), but has just enough to keep the pilot burning.

Hope this helps you to Troubleshoot the problem. If it does please leave me a positive approval.
Thanks!

Pilot light will go out when internal thermostat turns off main burner


Could be the thermopile or bad gas valve. Lets hope for a bad thermopile (costs much less). Are you able to re-light the pilot and does it stay on without the main burner on?

Keating fryer won't stay lit


You might want to see about getting your money back or swapping it for another. I'm guessing it is a natural gas model. If so check and make sure you have between 4 and 5 water columm gas pressure. If so I would start by checking the thermopile and make sure it's producing around 700 milivolts. If your not able to measure this or have the tools to do so, I would start by replacing the thermopile. (This is not a thermocouple.)If this does not fix the problem. You have a bad gas valve. Thermopile cost around $60.00. Gas valve runs around $30000You can go this web site for more info http://www.tmeinc.biz/xkeat.htm

The flame does not come on


Hello. Two things are possible. If your pilot is ok after lighting, and it goes out only when you additionally turn on the thermostat, most likely your thermopile is internally shorted, and is able to produce enough voltage to actuate the pilot portion of the valve, but opening the main part via the thermostat requires more load than the thermopile can produce, thus it now drops out the entire circuit.
The other is that your pilot is dirty, and is not heating the thermopile to a adequate temperature, to again, be able to handle the load of the entire circuit, as the thermopile is the only thing producing voltage/current for the heating circuit, thus no outlet to plug it into etc.. you could have loose/dirty connections, or low gas pressure, or one of the wires of the circuit is touching the frame, however, those are less likely from the problem you describe, not impossible, but less likely.
Hope that helps, and thank you.
