When I try to set my thermostat, it wont allow me to go past 32 degrees. Also, the air conditioner will not come on. The fan works though.
Same problem...then discovered my thermostat was set to Celsius instead of Ferinheight... pressed toe temp up and temp down buttons to change..fixed...
Thank you so much!! We searched Google for an answer as we were having the same problem and found this forum. We are currently are at the beach and even though one AC was working fine it can't do it all. So we were panicking and seeing $ signs. Your response not only saved the original enquiry I'm sure but thank you so much bc it saved us as well.
Thank you for this answer. I thought that it was the problem, but didn't know how to fix it. Happy New Year and God bless.

It could be the set up settings. Limits for Heat, for cool, or differential settings between the two, may need to change heating setting to allow the cooling setting adjustment. A installation manual may include instructions but take note of each setting before and after for ease of reverting.
You need to read the manual. There is a maximum heat and minimum cool set point setting in the programming. Possibly they have been set at those points. You are contradicting yourself on the cooling, to bring on cooling you turn the temp down, not up. Make sure you are on cool.

First I tried the reset did not work. Then cleaning ends of wires with cleaner - did not work. Try leaving the unit on fan all night. The sensor can get moister. Leaving the unit running will dry it out, Tried it on mine when it showed 32d. on the front air. It did show correct temp. on rear air. When i got up in the morning it was reporting the correct inside temp. allowing the air conditioner to come on. I think it was a moisture problem here in Fla.
Indicates inside sensor defective or not communicating resulting in a/c being locked out.

Hi,
That simply means it is not cooling...
To troubleshoot you will need to go up top and remove the cover...then check for power to the compressor... if you have power then check to see if it is running... if so then you have a refrigerant leak...if not the compressor is bad...
if no power then trace backwards to see where the power stops at...

Sounds like a stuck relay on the unit itself. Maybe there is a short in the control wire that comes from the thermostat that activates the fan.
The thermostat probably has one hot wire at all times. The thermostat then chooses which wire to send the voltage down based on your selection. One of those wires is probably for the fan only. Make sure that it is in good condition (no bare, pinched or wires)

16. SYSTEM RESET
a. Turn the ON/OFF switch to “OFF” position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to “ON”.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released.
c. When a dip switch is turned on or off after initial configu
ration, a system reset will need to be done before the
Comfort Control CenterTM will recognize the updated selection. Try this. This is for the five button thermostat. Did you check the dip switches to be sure the proper ones are turned on? I need to know which stat you have 4 or 5 button. I have trouble shooting for both.
If you notice reset needs to take place after a dip switch is turned on or off. The dip switches are on the circuit board. You need to drop the lower cover. the dip switches will read in this order #1 heat strip/ #2 zone2/#3zone3/ #4 zone4/#5 furnace/#6 differential/#7stag/#8 gen start. Check this out and be careful. Turn off the stat to change dip switches. On will be toward the description. If you don't have remote start gen set the dip should not be on. If you dont have a Zone 3 the dip should not be on, etc.
Any questions feel free to post back
Thank you for using fixya

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

Google dometic rooftop air conditioning parts!Wouldnt suggest using off brand parts maybe diffrent?if that one is set up for 12v also maybe deffinatley diffrent!!!Try cleaning condensor aluminum fins on roof top if condensor is dirty will throw whole system out of whack!!!use oven cleaner and hose with nozzle be careful not to bend fins throughly rinse off cleaner after soak period spray off completly off roof and sides quickly!!!!!may damage decals etc!!! anyhow try that before replacing parts then use factory or alike parts!!!Good Luck!!!
