Question

Air Conditioning Not Working w/New Thermostat?


Back in January we installed (ourselves) a digital programmable thermostat. All winter our heat worked fine, except when we had a few days in the 20's and it couldn't seem to get our house above 60 degrees.

Then today, turning on the AC for the first time, hot air is coming out of our vents. Before I call a technician, any ideas if this could be something we wired wrong when we installed the thermostat? ANy ideas of 2 wires that we may have mixed up?

Additional Info
Electric
We have 1 unit
Heat Pump
Unit is approx 10 yrs old
Serviced last April no issues
White Rodgers Thermostat Model 1F95-1277
The AC unit and all of its hoses/wires are not hot - running as usual/turning on and off

The factory default is MS 2. Change this to HP 1.

How did you wire it?

Yes, it has been on HP1 since we installed

Currently the wires I am using are:

O - Orange
Y1 - Yellow
G - Green
RC/RH - Red
C - Black (maybe dark brown)
W1 - White
W2 - Grey

As a side note - since you are looking at manaul - the Wiring Connection in the manual is slightly different then what is on the actual thermostat. The "Y" in the manual says Y1 on the thermostat - and "W/E" in manual says W1 on thermostat. Not sure if this matters.

Thank you so much for your help

Your heat pump wouldn't happen to be a Rheem or rudd would it?

I am not sure - I can check tomorrow. Would the brand name be listed on the unit?

Air Conditioning Not Working w/New Thermostat?


One more thing to add...I don't know if this is related or not. Late yesterday I noticed a slight odor in a few places in my downstairs. The smell reminds me on paint thinner or nail polish. Today when I woke up and walked downstair the smell is stronger (still not upstairs) and I can smell it just about anywhere downstairs.

Could my unit be leaking which is also causing the smell?

Sort of a sweet smell?

You probably have a short in your low voltage circuit, and the transformer is starting to over heat. And your smelling the varnish melting away.

Yes, I would say its more sweet than it is sour.

For the past few hours I have the ceiling fan going with open windows (its probably about 70-75 degrees here in NC right now) and the majority of the odor is gone.

And I called a technician who shoudl be here soon.

Thank you!

Problem solved!

First, the smell turned out to be not related. Turns out some gas spilled in our storage unit (outside but attached to house) from our pressure washer.

It was a wiring issue - at the unit. The tech was surprised it ever worked - but our old thermostat must have been wired incorrectly so that it somehow all worked.

The invoice reads "found reversing value wire not wired to the reversing value terminal at heat pump".

Cool, heat, and emergecy heat are all working.

Thank you - this forum was very helpful.
