Question about Heating & Cooling

Honeywell th5110d1006 not working

The thermostat doesnt really respond to anything I do to it. If I have the cooling set to 78 and the heat set to 75 and let it run on auto or even cool the ac will run into the 60s and won't stop until I cut off the power to the circuit breaker. If I put the heat on then it will go to that temp but strangely will still blow out cold air, so I'm not even sure if the stat is displaying the actual temp. Is this a thermostat problem or do I need to replace the circuit breaker?.......please help

SOURCE: Thermostat - Honeywell Chronotherm III

What you can do is try and clean the contacts. Open the door on the thermistat and remove the two screws, after that you can seperate the part that is mounted to the wall and the front panel. Look at the part that is mounted on the wall and you'll see the contacts that should be a copper color. They might be black from age. Clean them and you'll be surprised how well it will work after that.

SOURCE: AC STOPPED BLOWING COLD; ONLY BLOWS ON MAX MANUAL SETTING

Your AC is low on refrigerant; The AC compressor needs a minimum amount of regrigerant to run. If and when it does run (while low on refrigerant) the air coming out of the vents will not be cold. The refrigerant you require is R-134A and is available over the counter but if you are the least bit unsure as to how to add refrigerant, taking it to a garage that does AC recharging would be your best play. If you want to try to add refrigerant on your own you will need the following, 1LB can of R-134A, an AC hose adapter to deliver the refrigerant, and preferably an AC pressure guage to ensure you are not overfilling the AC line which will damage the system.

SOURCE: AC Fan doesn't blow cold air, frozen coil noticed outside, resetting power resolves temporarily

You need to call a reputable service technician.  The freezing up usually is associated with a low refrigerant charge or low air flow.  Check your return air filter and replace as needed.

SOURCE: Honeywell T8112 Air Conditioner Will Not Cool, But Blower Works

make sure the system switch is in the cool position, then press run program button and allow a couple of minutes for system to cycle on, if it doesn't come on press the button for lowering the set point, set it to 72 degrees and then press the hold temperature key.

Honeywell thermostat blows cold air on heat


Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

Amy,
It sounds like the problem is with the thermostat or how it's wired. I would call whoever the repairman works for and get them to send someone else out on a "call-back". (A "call-back" should not cost anything unless it is for parts)

You probably have it running a program. Try using it simply on heat mode. Then set temperature and press hold on thermostat. The word hold should show up on the screen.
