Question about Heating & Cooling
My roof top 7300 series shuts down after running for about a half hour on really hot days. The unit will run fine all night long. Turned all the way up I'm getting 52 degrees at the duct on high blower. How cold should the air temperature be? Run on low cool it will trip the breaker after about twenty minuets too. I normally have it set between half and three quarters on high blower. Am I looking at the blower motor as the possible cause or a capacitor?

(1)Check compressor contactor or relay if it stock in the close position
(2)Check for welded contact points
(3)Check switch control for defect

Is your condensing unit located in a well ventilated area and have an ample space, atleast a foot, from the rooftop flooring? Just make a check that free flowing outside air properly ventilates the condensing unit specially on high ambient temperatures. Hope this would solve your problem

It is definitely with the compressor. It should more like you may have a weak winding in the compressor, you can a hard start capacitor (sp5 ) that will help the compressor on restart. Note that this is a last chance solution for a compressor.

first off, it's illegal to release freon into the atmosphere. the epa could charge you $32,500, so keep it under your hat. second, if it's getting too cold where the evaporator coils are icing up, it's too lille freon, not too much. as for the breaker tripping, your compressor might be wearing out. if it's pulling too much current, the motor is failing and the compressor needs replacing. and do not do it yourself unless you're certified by the epa to move freon and have the proper equipment to recollect the used freon.
