Frig won't ignite on propane

Late model refers use the same probe for the ignitor and flame sensor. Not many have thermo-couples!
I would inspect the ignitor assembly looking for cracks in the porcelain. Inspect the high voltage cable for damage.
Bad circuit board!

check orifice and lines at heater for spider webs.. Use paperclip or pin to open if needed...

Don't use metal items to clear orifice. Soak in alcohol and then use compressed air.

Do you hear the igniter clicking?

Do you smell gas while it's trying to light?

Depending on the answers to either of those, is where you need to look at.

If you hear clicking and no gas, it's something with the gas valve solenoid or blocked line or?

If you smell gas, but no clicking, it's something with the igniter or whatever triggers it.

Good luck! Mitch

Make sure battery is fully charged. My fridge won’t light unless battery is over 90% even if plugged in to shore power.

OK---I could hear a click under the cover where all the wires come from, but at 81 I don't hear real well. No spark at the burner and I could not smell gas. Propane is full and battery is fully charged, I think. I will check that. Burner is a series of slots. I can only check when someone is here to turn it on, or switch from electric to propane at the refrigerator. Thanks everyone.

Turn refer on AUTO, Disconnect the 120 cord behind refer. Disconnect the 12 volt supply wire from the control board for 5 seconds and reconnect. The refer will now attempt to run on LP. You do this and you do not need a 2nd person. Doug

ferndale, I am sure you have tried this already, but when I had a similar problem, I put a thin nozzle on my air compressor and blasted away at the burner assembly.

It worked -- it must have been a particle of dirt.

Thanks Doug, I'll try that. Pro I have a commercial compressor and already blew it out real good, thanks.
