Get infrared thermometer and establish actual temps on elec vs gas.

You NEVER use a IR thermometer to verify refer or roof AC temps. In a refer you put in a glass of water. After 24 hours you use a digital thermometer to measure the water temp. That tells you the actual cooling of the refer. Doug

I’m having no luck balancing a glass of water on an ac duct.

If it works on 120, but not on LP.
1. LP pressure is not at 11.5 inches w/c. just 1 inch below will have a drastic affect on cooling.
2. The burner is dirty. Doug

Fans controlled by that thermostat run based on Condenser Fin temps....not on which heat source is being used

Fans ON...130*F fin temp
Fans OFF...115*F fin temp

1A in-line fuse on DC + to thermostat

Would it work on electric but not gas if that happened?

The snap disk thermostat on the top coil in back is known to fail and the cooling fans won't come on. Check that.

No kidding - mine lasted one weekend when it was new.

Cooling unit is functioning hence the cold freezer/food compartment using electric

Freezer only cold/food compartment not using propane.....that is because the propane is not transferring enough heat to boiler to change liquid ammonia into ENOUGH vapor that can be condensed into cold liquid to absorb heat from freezer AND food compartment

Propane system pressure...first thing to MEASURE
Hard to visually check if it is sufficient or not
11"WC is 0.4psi
9"WC is 0.32psi
0.08 psi difference...can't visually see that


2nd check.....burner flame
Strong steady and reaching up into open bottom of flue
(burner slots fully open)

Then you pull flue baffle/clean it up (soot/rust) and clean flue walls

Shouldn’t be rusty yet but clean/ check flame height, clean flue.

Try a battery operated fan in the fridge section. Worked for me since 1978.
