Just a normal propane fired furnace with an "A" coil and a compressor
outside. When the thermostat is set to auto fan and cool the inside
circulating fan in the furnace comes on but the neither the outside fan
nor the compressor come on. There are two breakers, one in the main
breaker panel and then another outside near the compressor. When the
both breakers are on I have 220V going to the compressor thus that is
not the problem.
When the thermostat is turned to cool there is NO sound at all at the
compressor.....not even a a relay closing.
Unfortunately the thermostat is a programmable LUX and it is my opinion
this is where the problem is. On the other hand, when set to cool, the
inside circulating fan does come on.
Your comments and suggestions would be welcome.
