SOURCE: My Dometic rooftop Ac/heater runs for approx 6hrs then shuts down and then you hear a humming sound.Turn it off for approximately a hour or to turn it back on and it will work again.

If it runs for six hours its not heating very well

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.


The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Sounds to me like your fan is hitting something
Remove the cover and turn the fan by hand ( with the power off ! ) See what it is hitting

Air conditioner fan will not come on and unit will run for 1 minute and stop


You hear the compressor kick in (Hum) but no fan comes on? Will the fan come on when just in fan mode, not cool, or do you have that set-up?
