5. COMPONENT: ROTARY COMPRESSOR WITH
ACCUMULATOR (CONTINUED)
TROUBLESHOOTING (CONTINUED):
Check winding resistance of each terminal. If resistance
value is 0 ohms or infinite, replace compressor.
RESISTANCE BETWEEN EACH SET
OF WINDINGS SHOULD BE EQUAL.
6. COMPONENT: COMPRESSOR TEMPERATURE
OVERLOAD PROTECTION
DESCRIPTION:
If temperature detected by the overload sensor exceeds
239ºF (115ºC), the compressor will stop and the outdoor fan
will stop after a delay of 30 seconds. Once the compressor
temperature drops below 204ºF (95ºC), the compressor
overload protection feature will reset and the system will
resume normal operations.
TROUBLESHOOTING:
* Check wiring connections at compressor terminals and
at the outdoor control.
* Check control SAT to determine if it is closed or open.
If resistance is infinite ohms, then the overload control
is closed. If the resistance is 0 ohms, then the overload
control is CLOSED. If the compressor is not hot to the
touch, then the overload control assembly should be
replaced.
