Well, teased you enough about the thermostat. That's a really, really
old joke on this list.

At this point, one of a couple problems come to mind. It's possible
that the thermostat wire is worn through,a nd shorting.

But, more likely there is a sticky relay inside the furnace which is
not releasing. It is time to call a HVAC repair company. Another
thermost is not likely to change anything except the thermostat.

Please let us know how things work out.

I am hoping that someone might have a suggestion.....

I bought a ritetemp digital thermostat from Home Depot. I have a two
wire system, one white and one black wire.

I followe the instructions for 2 wire wiring and everything worked
fine. Two weeks later I came home to find the furnace running
eventhough the thermostat was in the "OFF" position. I returned the
thermostat and got a new ritetemp digital. I wired it up and I am
having the same problem. I reversed the wires and there is no change.
I have one wire to the "W" and the second to the "RH" that has the
jumper.

Is it my wiring, the thermostat or an issue at the furnace?

Please dont.

Hey Chrissy boi...what relay would that be? I have a feeling that hes got a
gas unit, UNLESS of course its an electric, and then chances are, its not a
RELAY, but a sequencer, and that makes much more sense..but hey...your ball
aint working..since you cant see what the issue is over the net eh? Unless
of course, one of your magical Mormy aliens told you the issue.

Hey..you wanna show professional internet troubleshooting?
Show us...here is a simple one.

Customer calls. Has a LuxPro stat that he wants wired. Simple enough. 4
wire. No common. Just R, G Y and W......old stat was a simple COOL ONLY
White Rodgers mercury stat.
Sep T87F for the electric furnace...Coleman if it matters..
The Lux is for the Gas-electric thats wired for AC only....leaving the W out
of the equasion above...Old Day and Night, if it matters to you...
Now..here is the issue, and think about it real careful, cause it took me
about 20 seconds talking to the owner to get that information posted above
to know what the problem was.

Issue: When the Lux was turned to ON, fan position, the blower would start
and run fine.
When the stat was set to AUTO, and COOL, and turned low enough that the AC
would start, the compressor, condensor fan motor and nothing else would run.
IE: No Blower.
Now, it runs fine, no matter what the setting, remember....heat is NOT used
on the old gas-electric package unit..the gas valve is not even in the
unit..

The repair was simple as pie...what was it?

No parts replaced.
No stuck relays..
No more than a service call and 20 minutes of time to insure it all worked
and worked correctly after a under 5 minute repair.

What was it?

Amaze us with your tech ability. Any tech thats been in the field a bit can
figure out basic electricity. Lets see how much knowledge you really have,
and regs, please leave this one to the new internet god of repair advice.

Id bet the farm you aint got a clue, and if you dont Chris, be man enough to
admit it.

I'll admit I've not used one of these thermostats. But, from what
you're describing, I've got two ideas. The first is less likely.

1) there is a switch inside the thermostat to change from heat pump
to split system. Causes the therm to supply signal to the G lead (or
not).
2) The new thermostat shoulda been wired to Y2 instead of Y1, at the
air handler. Or the other way around. Y1 instead of Y2.

Since the customer replaced a two wire stat, you didn't say if s/he
pulled a new wire. But we'd have to guess s/he did.

Well, th at leave the yellow wire to YH or YL at the air handler.
