Try a new overload or compressor
Pull the fridge away from the wall, unplug it and remove the service panel. Swap in the
new compressor and overload relays. Then plug it back in to see if the problem is gone.
A refrigerator that makes a buzzing or
humming sound and doesn’t keep the
food cold may have a blown compressor
(big bucks) or just a bad overload or
compressor relay (about $20).
I had this exact problem with a
refrigerator and called Costas Stavrou,
our appliance consultant. To avoid n expensive service call, Costas suggested I
first try unplugging the refrigerator
for about 20 minutes to allow enough
time for the compressor to cool and
any on-board computers to reset.
When I plugged it back in, the problem
returned. So he suggested I buy both an
overload and a compressor relay (or a
universal relay kit) from the appliance
parts store and install it (see photo). If
the problem went away, it would be a
$20 fix. Unfortunately, my compressor
noise returned (meaning it was toast).
I had to buy a new refrigerator, but at
least I didn’t have to waste money on
a service call. Instead I applied that
money toward a new fridge.
