Spt portable ac question. When I turn this on it sounds fine but there is a red link got where it says comp. and the compressor does not kick on . What can I do to fix this?

SOURCE: AC does not cool. Compressor kicks on and off (Humms when trying to start, electrical smell)

There are a couple possibilities:

1. If this is the first time you've started them for the season, one of the compressors might be seized up from sitting over the winter. In which case, new compressor required.

2. If you've just had the compressor serviced including recharging the system, it's possible that the system is simply overcharged. This will stop the compressor from working and giving you the same symptoms as above. If this is the case, you should have the service people come back with some guages and recover some of the refrigerant and the compressor should be fine.

3. If the unit has been sitting and there is a slow leak then there is not enough pressure in the system to allow it to run. The compressor will shut down if there is not enough pressure, but since you say there is a smell, i really doubt this is the case.

Most likely it's #1 or #2 above. If you haven't had it serviced recently, then yeah, it sounds like you're in need of a new compressor.

Good luck.

This is a single speed permanent split capacitor motor for the condenser. One of the capacitor wires shows infinite resistance to hot and netral. The motor needs to be replaced.

Most of the time the capasitors are bad but it could be that the commpressor is bad or if it is a heatpump the low pressure switch could have it locked out or the contactor could be bad also

If this is the kind I'm thinking of the condensate tank needs to be emptied of water.
