High Temp Safety
The High Temp Safety is a bi-metal thermostat
strapped to the line at the outlet of the Hot
Gas Valve. Should the Hot Gas Valve stick
open and the refrigerant line reach 180
degrees F., the High Temp Safety would open,
dropping power to the Contactor and shut
down the Compressor. When the line tem-
perature drops below 120 degrees F., the con-
tacts of the Safety will close, allowing power
to the Contactor.
Troubleshooting
Should the Compressor not run with the R2 relay LED illuminated, verify if High Pressure Cutout
is closed and Contactor coil is good. The discharge line from the Hot Gas Valve should be cool to
the touch during a freeze cycle. With a line temperature below 120 degrees F. (confirming hot
gas valve is closed), the contacts in the High Temp Safety should be closed. Disconnect both
leads of the High Temp Safety and check for continuity. If open with a cool line, the safety will
need to be replaced.
