Outdoor unit keeps tripping what I believe is a high

Customer Question

Outdoor unit keeps tripping what I believe is a high pressure switch. It'll come back on after I manually reset it but only for a short time.
JA: Did you double-check the thermostat? And what about the unit's filters?
Customer: Filter was just replaced a week ago and the thermostat is set to cool at 70
JA: Do you plan on doing the work yourself?
Customer: If at all possible I had someone out to look at it...all he did was spray the coils off with my hose and say I need a new unit
JA: Anything else we should know to help you best?
Customer: The guy Said the pressures were running too high and the fan was was putting out to much voltage?!

hi i am dan i can help you with this. that will definatley be a high pressure switch on the unit. the only way to determine the cause would be with a manifold gauge. but most likely you do not need a new unit. one possibility is a dirty condensor coil. it needs to be cleaned out with a coil cleaner and then rinsed out from the inside out. another possibility is the fan is not working. or there is a restriction of refrigerant flow somewhere in the system.
