The unit is on Heat, Fan Auto it's 36 degrees outside, Thermostate set on 73 Actual temp inside 70. Unit runs continuously. How can I get more heat. I tried Emergency heat and that doesn't help.


Have you cleaned the air return filters ? Wash them, don't vacuum or brush them. It damages the filter screen. Sometimes a thermostat will be out by a few degrees. If the filters are clean, try turning the temp down a bit to 65 degrees and see if the air con shuts down. ( If your room temp is showing 70, it should switch off the machine) If it doesn't turn off, keep reducing the temp by 5 degrees at a time and wait a few minutes each movement to see if and when it shuts down. If the machine keeps running, I would suggest your thermostat is shot and you will need a new one.

Rheem split system condenser high pressure limit/safety needs resetting frequently before it reaches the set temp of 76 degrees faren. what's wrong and what do i need to check?


Is the outdoor fan running? The fan cools the coils and compressor, therefore keeping the high pressure low enough to run. Either the fan is not working or its not spinning fast enough. Check the capacitor, or just replace it.

AC Condenser motor will stop at 1pm but inside unit is still running but no AC. If I turn the AC unit breaker unit off and then an hour later turn it back on. The unit runs fine all day until 1pm. Had a...


Hi, the tech should have been able to figure the stat out with out a manual to see why the condenser is shutting off at 1:00 P.M. This is unusual for this to happen, unless it was winter and this is a heat-pump going into defrost, but just the fan would shut down. Does this unit have a box on it that was installed by your electric company that shuts the unit off during high peak conditions in the summer? This would cause it to shut down at the same time everyday. If not, it would have to be something in the thermostat that is set for it to shut off at that time. It still does not make since, as it would shut both the indoor and outdoor unit off, not just the condenser. Are you saying that just the condenser fan motor is shutting off, but the compressor continues to run until it shuts off on high head pressure when the fan stops, or does the complete outdoor unit shut down fan, compressor and all at that time??. It sounds to me like this outdoor unit has a time delay relay that has a fault in it may be shutting it off at this time daily? Please let me know if its just the condenser fan motor that shuts off, or if the complete unit is shutting off all together, this will help .
Sincerely,

Possible Contactor Issue


Sounds like a bad fan switch in your unit. That unit has a fan board in it that is time delay on and off. Turn the fan to the on position and let it run all the time. If it keeps temp and does not shut off it is the fan realy board. The board also controls the compressor. Check that first and then the tsat. Russ

Fan isnt running


If the fan on the condensor isnt working but yo still hear the compressor going you might have a bad fan motor. or the coil pack is bad. its a cylynder shape part which should be located by all the relays in the condencing unt outside. Generally easy to get to, make sure the power is shut down before opening the casing. Them pack do go bad do to weather factors. If it rusty and you can shake it and it sounds like theres water in it, then its bad. The pack usually has 3-4 wire connected to it, Remember the order of them for installation. This part runs from anywhere to 20 to 30 dollars on norm at grainger. I replaced mine last year and it worked once then the fan quit. They said the coil pack probably shorted the fan. 65 dollors there. After put back together, runs like new, and i did it my self, with just a little knowledge of HVAC,, Good luck, But first thing to do is make sure your breakers are on, ive seen that a couple times, lol

Unit will not shut off by itself.


A/C only will not shut off would check for low refrigerant charge. If furnace also will not shut off (remember fan will run for short time before shutting down) then either thermostat is wired wrong or control board is defective

CARRIER HEATER FAN WONT TURN OFF. PLEASE HELP


Need more information.... Is this a whole house unit, a window unit or what? Model #?

The breaker would be in your basement or wherever your breaker box is. If it's a 220 unit, one side could be kicked if whoever hooked it up used 2 seperate breakers (very unusual but it's been done).

Good luck!
