Thermostat Replacement (Lux brand)
 

Our old thermostat decided to quit so I am trying to replace it with a
"Lux" Brand from Lowe's.

What's happening it the Heat will turn on if we set it to heat and raise
the temp, but the Air conditioning won't activate mo matter what.
Once when I turned the switch to FAN the circuit breaker cut power.

The Central air unit is fairly old... Here is a picture

Here is a picture of the thermostat's innards and how we have it wired:

Hopefully I won't get flamed as badly as I did in the other group.
The model is CAG1500
there are five wires: white, yellow, green, blue and red.

Hi,
What was your old 'stat? Lux is considered junk 'stat.

Not sure what the blue wire is being used for, but you probably need
the jumper in between the RH and RC terminals.

I can't see the photo. The web page wanted to install something and then it
went to an advertisement.

Take the Lux back and get a Honeywell.

It doesn't sound like you have a thermostat problem. If turning on the fan
trips the breaker, you probably need to check the blower unit

If you touch the blue thermostat wire to the yellow wire, your condensing
unit should come on. If you touch the blue wire to the green wire, the
blower should come on. If these things don't occur, you have a problem
somewhere other than the thermostat

People tell me I have problems.
I'll call the contractor tomorrow morning.

Be careful with the colors. I've lived in two houses where the
thermostat cable was spliced somewhere, and the colors on the wire
didn't match the colors labels on the thermostat. Very frustrating.

Thermostat Replacement (Lux brand)
 

Several ears ago I bought a Lux thermostat to replace an old round
inaccurate one.
I also had a subtle problem in that some thing did not turn on as expected.
I don't recall if it was the A/C or not.
But go back and check the directions carefully. The Lux was shipped set up
for gas heat (IIRC). There is a small change you have to make to set it to
work on all electric.

Hope this helps

When you replaced the subbase, did you wire it back as the same as the first
stat?
If it is the same, you can use a jumper to check the system out by:
RH (Power to Heat) jumpered to W (Heat) then the heat should come on.
RC (Power to Cool) jumpered to G (Blower) then the inside blower should run.
RC (Power to Cool) jumpered to Y (Outside Condensing unit) should come on

When I replaced my thermostat, I checked the connections (at the
thermostat), and wrote those on a label I stuck on the furnace (along
with the filter size, another piece of useful info).

I fixed it.
Cool air is flowing as we speak. It kicked off, and then kicked back on
just like its supposed to.

I see the problem right away...the unit has tipped over and fallen on its
side.
