Overload
The overload provides protection to the compressor
motor by responding to both temperature and
current. The overload consists primarily of a bimetal
element and a set of normally closed contacts. The
auxiliary heater is for a faster response.
The overload is connected in series with both
windings of the motor. If the motor fails to start
for any reason, the “high” locked rotor current will
cause the bimetal element to heat, snapping the
contacts open and interrupting current flow through
the motor.
The motor will continue to cycle on the overload so
long as the original reason for tripping persists.
Run Capacitor
The run capacitor plugs into the combo device and
the same disassembly and safety procedures apply
(
ALWAYS DISCONECT POWER
).
Run capacitors are used with single-phase
compressor motors to increase the running
efficiency. The run capacitor is connected in parallel
with the PTC, and is shunted while the PTC cycling
control closes for starting, but is utilized along with
the start winding after the relay contacts open and
so long as the motor operation continues.
Combo Device Removal
1.
Disconnect power to the refrigerator.
2.
Remove the four 1/4 in. hex head screws from
the rear access cover.
3.
Remove the combo device retainer (needle nose
pliers work well in removing retainer).
4.
Remove the protective sleeve off of the
capacitor.
5.
Disconnect the wiring.
6.
Disconnect the capacitor from the device.
