Should my condensor fan run when heat is on?

Real basic question I think about HVAC.

I replaced my thermostat on our HVAC system the other day and when i
kicked on the heat, it turned on the fan that's in the condensor
outside (that big thing I usually associate with air conditioning). is
that normal? I don't remember that thing ever running... the heat
works, I just wasn't sure if that fan is supposed to be going...

It's an electric system, if you need to know....

Thanks everyone...

You sure are some kind of **** up. If the condenser fan is on, so is
the compressor. Call someone who knows what they are doing and thats
NOT YOU!

anyone have something a little more insightful to add to this?

Actually, I have questions. From your comments, I want to assume this
is a seperate Electric Furnace/A/C Condenser setup. Could this be a
heat pump?

Also, while there are some very different exceptions (i.e. advanced
thermostats not available through home centers, etc.) , if you wired
the thermostat as the original you should not be experiencing this
problem. While the terminals seem to coincide with colors, they do
not. . . they have meaning. Also, although not necessarily your case,
color blindness is a real fact in our society. Very severe color
blind technicians will mark wires and ohm them because color has no
meaning (the truth, the wire does not care what color they are
either).

Tell us what model thermostat you installed and tell us what wires are
set up to what terminals (although color is subjective, some of us
will give them the benefit of the doubt) And make sure your
installation instructions are handy. Yours is not the common problem
I find with homeowner installed thermostats (jumper missing from RH-
RC), this appears to be betwen other terminals. Are your connections
clean?, meaning are any metals touching?

No problem. Just use the Garage door remote to turn it back off.

Electric system?? Thats like saying your replaced the keys in your car and
it runs on gasoline. Is it normal for it to make that noise??  WTF???

How about post make, and model..... if you can't figure that out, is it
straight a/c with strip heat?? or a heat pump??

The new one is a Ritetemp 6060. I replaced a robertshaw thermostat.
I have all the colors connected correctly, the ritetemp people
verified it... i'm tihnking that a jumper is off.

I don't know about it being a heat pump, i'm sorry...

Sorry Dwarf but if you cant figure out whether or not you have a heat
pump you had ABSOLUTELY NO BUSINESS replacing a thermostat.

this is the unit I have outside, apparently - it's a heat pump. Ive
noticed the fan on the unit only runs for a little while - and then
stops. I thought heat pump fans only turned on when it was really cold
out? it's only like 50 here...

either way, the heat in the house is working... i just wasn't sure if
this was normal.

Robertshaw, [if my memory serves me correctly] makes many different types
and styles. Do you know which one you have? Because if you have a heat
pump, it could require a 'special' thermostat. On the other hand, if you
have electric heat with a heat pump, that could require a different
'special
thermostat.' But if you have an electric strip heat, and split system
air
conditioning, then you might need a standard - special thermostat.

You probably better ask Bubba. He's the resident expert on thermostats!
Im still wondering that........if he has all the "colors connected
correctly" how did all those low voltage electrons figure out which
color to go through first and HOW did the "ritetemp people verify:
that those colors were the right colors?
Im thinking that the electricty is just confused with all those colors
and the OP needs to run new polarized shielded stranded low voltage
low loss wiring with a new color matching shielded non polarized
digital set back thermostat.
That should take care of the fan problem.
Bubba
Need to find out first if the wires are twisted clockwise or counter
clockwise

Only matters below the equator wire spools run counter clockwise to negate
the coriolis effect.
So you have to run the wire off the spool completely and start running from
the inside end (tic)

One comment I would make:

If you didn't buy a heat pump thermostat, and the PROPER t'stat (1 stage
cool, 2 stage heat IF that is what you have), then you may get a big
surprise when your electric bill comes....
