Compressor won't run or it is "clicking' on and off:
This normally could be a bad start relay and over load for the
compressor, dirty condenser coils need cleaning, condenser fan motor is
not running or the compressor itself. To check the compressor properly
you should test it with an amp
meter, each compressor is rated in running amps ( see model/serial tag
or the sticker on the compressor )...if the compressor is drawing too
much current, this may be why it is shutting off. Check the model tag
for proper amp rating. Some relays will be easy to notice the broken
with them, they may be burnt. Some of these
relays can be removed and give them a little shake, and if they rattle
around inside the relay is likely bad. Compressors can also seize and
click on and off or one of the electrical windings inside the
compressor could have opened up. You can use a test cord to help check the compressor and this also will help with the amp test. If the compressor checks ok and you want to install a replacement start relay. You will need to find out which winding is which. You will need an ohm meter to
determine the windings. First check to see if you have windings in the
compressor. Then check to see if they are grounded. If the compressor
has windings and they are not grounded, you can find which winding is
which. Check for grounded windings by reading from each terminal to a
good ground on the cabinet. Read from the top terminal to the lower
left terminal. Read from the top terminal to the lower right terminal.
Read from the lower left terminal to the lower right terminal. Write
down the resistance of each reading as you go. The highest reading you
get will be the run and start winding of the compressor in series with
each other. The other terminal left will be the common terminal. Read
from the common terminal to each of the other terminals. The terminal
with the lower resistance will be the run winding. The higher
resistance the start winding. Using the original style relay is always
preferred, but using a general replacement can "get you by" if needed.
