If you are confirmed that the thermostat is not cutting off the compressor, then it is possible that the thermostat is faulty.
You will have to check if the compressor is cooling the room properly , If not then the thermostat is not getting up to the set temperature . In such a case reduce the thermostat level and see if the compressor cuts off. If so the compressor is not cooling to the extend that it ought to then have the gas pressure checked.If low
fill up or if the pumping is bad then then the compressor might be defective.

How do I determine reason that my Danby Dehumidifier isn't cycling on to compressor for more than 3-4 seconds at a time? Fan always runs but compressor only kicks in for 3-4 seconds then back off.


I would say low on gas or bad switch/thermostat.
The compressor probably has a shutoff for low freon. You would need a set of gauges to check for that.
Bad thermostat? You'd need a ohm meter.
User error? What kinda settings or controls do you have on the control panel?
There was a recall on these in 2014 for catching on fire.

My domestic rv ac unit reaches the temp setpoint and the compressor shuts off but not the fan, it just keeps on running. Is this normal or should the fan shut off also?


Set fan setting to auto and not high or low setting. Fan will cycle with compressor after setting set to auto or " au" if a digital thermostat.

Will not stop running


Are you referring to the compressor not shutting off down below or the evaporator fan inside the cooling area not shutting off? Evaporator fan always runs the compressor is controlled by the thermostat you could have a bad thermostat if the compressor never shuts off.

COMPRESSOR RUNS A LOT


Your model has a mechanical thermostat inside the control panel. I believe you have something else going on like a bad fan, start relay, capacitor. Something is causing the compressor to struggle to keep up and in turn causing the compressor to short cycle. If the thermostat has no control over run time then something like I explained is causing the problem. Here is a parts manual=> ED5VHEXVB04 Contact me if you would like my help, Thanks Sea Breeze

Amana ACD125R compressor will not turn off without unplugging


If it's a mechanical thermostat, then it's electrical contact points must be closed for some reason. If the thermostat is electronic, then the logic board may be fried. Either way you would have to replace the thermostat.

Yes you are right the thermostat is not responding to switch off the compressor at the desired temperature setting. It stay "always on" position. Replace the thermostat to rectify this problem....................sodeep
PS: low refrigerant gas could also contribute to aggravate this problem, so have it checked too by the repairman.

A/c unit not working


So only fan is running, the compressor not running okay check the voltage going to the compressor. The connection is coming from Thermostat or temperature controller, if there is supply going to A/c Comp. check the safety thermostat relay above the compressor.

AC/Heatpump units cycle numerous times blowing ambient air.


If the compressor never kicks in, I would check the start capacitor, thermostat and the compressor windings. Most times the start capacitor is defective. Some window air conditioners the fan will run while the compressor stop through the thermostat switch. If the thermostat switch is bad every thing runs except the compressor. Let me know, Thanks, Sea Breeze

Refrigerator/freezer gets warm intermittently


sounds like your thermostat is faulty
the thermostat reads the temperature of the cabinet and controls the temperature
the 1 thing to check on the uprights is the evaporator is in the freezer and that makes the cool then there is a fan that blows the air around the fridge and freezer to freeze things
now there is a cycle that hapens to cycle usualy every 12 hours and that is the defrost cycle
this cycle turns off the compressor and fan turns on an defrost element on the evaporator and heats up the coils to get rid of the ice
the ice turns to water and runs through a drain to a evaporator tray and when the cycle is finished the fridge stars up again and goes into the cooling state again
when the thermostat decides that the fridge is cold enough it turns of the compressor and so on it goes through the cycles as required
if the drai is blocked or the defrost system is not working the evaporator will get choked with ice and the fan will not beable to let air through to cool things off
