Coleman TSR RV air conditioner doesn't blow cold- Doesn't need a charge
We have a 1986 Terry Taurus triler with an a/c unit that only says "Coelman TSR" on it. No model number.
The numbers that are on the label for the thermostat switch are:
A30 1813 00
P166 24 SA
The knob that controls the heat and the a/c temperature does not appear to be sending an electrical current to the components in the rooftop unit. The fan works on all settings, but we don't get heat or a/c; only ambient air temperature air flow.
A friend tried to give it a freon charge, but that didnt allieviate the problem because the compressor does not appear to be turning on.
