Air Conditioner Not coming on
While camping last weekend we noticed that our Duotherm/Dometic AC would only come on when the thermostat was pushed above 85 and would shut off below that. It was operating like an on/off switch. We got by just by running it for 15-20 minutes to cool the 5ver down and then shut it off for an hour or two. I thought this was a sign of the garbage thermostat going bad, and so opted for a non-programmable Hunter from Lowes. I believe I have it wired correctly. I can get heat and fan to work, but no AC. I have the ground (black wire) run to Rc (with a jumper to Rh), the heat (white wire)to W, the high and low fan wires (blue and orange) are both ran to G on the Hunter (just trying the blue, high fan wire would not make the fan run), and the AC compressor (yellow wire) to Y on the hunter.
I can jumper across from the fan to the ground and the compressor to the ground and get the AC to kick on, but the thermostat will not activate it. I tried to rung the high speed fan and AC compressor together on the Y terminal, but had no change.
I don't even hear the thermostat click on in AC mode, but I do in heat mode. All wire connections look tight on the inside of the AC unit.
Do you think I have a different problem with the AC, or do I still not have it wired correctly?
