First, the normal color of the pilot flame is blue. When the flame appears yellow, burners should be inspected and cleaned. Is your heater pilot blue or yellow?

If the pilot seems fine, then I would test the ignition module. The good news is that if you are electronically inclined, I have a manual with the wiring diagrams so you can see how everything is wired up in order to test the parts and I also part numbers on it. So please check the ignition module if the pilot seems fine and use the manual to further branch back from the ignition module to find out why the burners don't all light. Another possibility to look into is gas pressure to all of the burners. Here is the manual on the following link.

Let me know of any further questions.

Where can I find helpful instructions for replacing (removing old and installing new) thermocouple on Pentair 250k minimax ch NG mv? Thank you.


Simple:
  • Insecure bracket holding the pilot assembly to the burner tray
  • now, remove the pilot assembly from bracketry
  • unscrew old pilot generator/thermo pile or thermocouple
  • new may have a clip instead of threaded nut
    • diameter of hole is same so it should just snap into place
  • in reverse order resecure the pilot bracket to burner tray

Do you have 24V at the brown wire of the gas valve? If you do then it is probably a bad gas valve.
If you don't have 24V on the brown wire it is probably the ignitor.

Pentair Minimax CH Propane Millivolt Ignition Heaters error E05 what is it?


If you are firing, and then going off and getting an E05, your igniter is to blame. It may be glowing but it's getting weak. The diagnostic goes further but that is usually the fix.. With inactivity, the igniter is always to blame. You really need to fire it off weekly to make it reliable and make sure that your heater is serviced at least one time a year to keep all the internal components operating as designed.

I have a minimax 250 i can light the pilot but the main burner will not light. i jump the th to th/pp and the pilot goes out.


are you sure your jumping th and th/pp? the labeling on valve is a little deceptive.should use 1st and 3rd terminal on gas valve. if your using correct terminals try same thing with thermostat wires disconnected from gas valve. this will isolate valve from all controls and safties.if it fires valve is good and need to look in thermostat loop for problems. hope this helps

Main burner not lighting


Could be bad coupler or pilot valve is not staying up due to bad spring. If the light does stay lit at all, then the problem is with the fuel.

You can get the entire pilot assembly for $70 at poolcenter.com
