Low or no refrigerant Blown Fuse Defective pressure switch Bad clutch on compressor Selector switch
Open circuit breakers. Poor electrical connections to the compressor, thermostat or bad wires not telling relay to cut the compressor on. Elaborate
Because the air conditioning compressor, is run from a pulley off of the engine. This puts an additional load on the engine, which causes more fuel to be used.
Bad clutch on compressor, unplug the wires from the AC compressor, replace fuse if doesnt blow fuse its in compressor, if blows then gounded wire
We are afraid to use the unit 24 hours because it might cause to overheat .What is really the cause of overheating?
Air conditioning systems can stop working for several reasons. The most common reason is that the fluid charge has leaked out. Other causes include a disconnected wire, a worn compressor clutch, a broken belt, a seized compressor, a clogged expansion valve, and the list goes on...
If the heat is on that would explain it. But if you are running the air conditioning, the compressor is on and fully charged with r134 it is probably the air mix door inside the heater stuck in heat mode.
Engine vibration can be an indication of a misfire, but more often it's just the AC compressor causing a little shaking.
A stuck compressor contactor. Do not turn off the indoor fan until you have either shut off the breaker or pulled the fuses to the outdoor unit and stopped the compressor, or damage may result.
what causes compressor lockout in voager rooftop unit.
More than likely it is short on charge. Best to turn it off until the problem whatever it turns out to be is corrected. Short cycling is not good for the compressor.
Check the following............................. 1. Cooling fan operation. 2. Radiator cap. 3. Thermostat.
Liwuid refrigerant would make ist's way back to the compressor and may cause damage to the valves and alos will dilute the oil which causes bearing failure.
