III. TROUBLESHOOTING
III. e - PROPER SENSOR PLACEMENT:
Coil Sensor:
The coil sensor should be inserted into
the return air side of the evaporator coil.
On freezer models only this sensor
should be centered approximately 2”
(two inches) from the top (horizontally
through coil - centered in coil).
On refrigerator models this sensor
should be mounted on top of the coil.
Cabinet Air Sensor:
The cabinet air sensor should be
mounted inside the evaporator housing
(hump) on the return air side of the
evaporator coil.
Discharge Sensor (R & A Series Only):
The discharge air sensor should be
mounted on the hot gas side of the
compressor. Placement should be as
close to the compressor as possible
and must be placed prior to the
beginning of the hot gas loop. Please
note that discharge sensors must be
insulated.
