Rooftop AC cycling

[Stopher50]

Like the title states. Compressor kicks on for about 20 seconds then kicks off for a minute then restarts over and over. Voltage is good to the trailer and replaced the capacitor. After about 5 or 6 cycles it stays on. Seems to be getting worse as time goes on. It’s a domestic unit not sure which one

Did you check for loose wiring?

Did you reset the thermostat?

It almost sounds like a weak contactor dropping out. Have you checked the roof top and cleaned the fins to ensure good airflow?

Thermostat or control box. Control box has a relay that powers the compressor. Thermostat tells the relay to close so it can cause this. What thermostat is in the system?

 

[jackieo]

when the last time you cleaned the evaporator?

 

[Holdmybeer]

Most common cause would be low freon and then ice on the coils ( the latter a condition caused by low freon).

 

[John&Andrea]

Just curious what the issue was with your A/C?

Like Holdmybeer said, it's probably low on freon.
