Why does a compressor take 5 minutes to restart?
Also, compressors in heat-pumps have a five minute time delay to protect the compressor from high pressure due to switching from heat to cool or vice versa. The 5 minute time delay in this case protects the compressor from high pressure caused by the change in the flow of refrigerant at the reversing valve.
What causes a delay in the start up of my air compressor?
If your outside unit isnt cycling on and you have line voltage coming in to L1 and L2 first thing I would check is the contactor you say it does come on.If its cooling when it comes on the your condensor fan and compressor are working fine. Likely a relay timed to close (tc) and create a delay.
What happens when an air conditioner compressor stops?
if an air conditioner compressor stops, it still has pressure built up inside. This pressure prevents the compressor from easily starting. There is a safety switch that won’t allow the compressor to start until the pressure bleeds off. If the compressor tried start with pressure in it, the unit is essentially “locked up” and would blow the fuse.
Why does my air conditioner have a restart timer?
Air conditioners operate in an environment where there is considerable head pressure to liquify the refrigerant. It may exceed the starting torque of the compressor. The restart timer gives the system time to allow pressure to equalize on both sides of the compressor, reducing starting torque allowing the compressor to start without stalling.

Why does the reset button on my air compressor always trip?
If the compressor reset button always trips on your compressor, the motor is getting too hot! Check to make sure that your air compressor is plugged right into the wall socket, and it is not being powered through an extension cord or power bar.
What happens if your air compressor overheats?
If the motor overheats, the thermal cut out will shut it down. If you are using your air compressor for extended periods, more than, say, ten or fifteen minutes at a time, the typicaly DIY air compressor will overheat. The duty cycle of the compressor may be less than the time you are requiring it to run, and the motor will overheat.
