F−Compressor High Temperature Limit
(Early Models)
Each scroll compressor in the HS26−261, −311, −411, −461
is equipped with a compressor high temperature limit lo
cated on the outside top of the compressor. The sensor is a
SPST thermostat which opens when the discharge tem
perature exceeds 280

compressor contactor and the time delay is de−energized
and the unit shuts off. The switch automatically resets
when the compressor temperature drops below 130

The sensor can be accessed by prying off the snap plug on

seal the limit after replacement. The limit pigtails are lo
