GE TEMPERATURE CONTROL ADJUSTMENT FOR
HIGH ALTITUDE APPLICATIONS:
REQUIRED TOOLS:
• Jewelers screwdriver (Small screwdriver)
GE CONTROL INSTRUCTIONS:
The scale to the right may be used as a guide for measuring
degrees of rotation required for altitude correction. See
Figure 1. The arrows indicate direction of screw rotation.
Turn calibration screw clockwise to obtain warmer operating
temperatures.
STEP 1 - Unplug cooler.
STEP 2 - Remove the screws that secure the temperature
control to the inset box.
STEP 3 - To make these adjustments it may be necessary to
remove the temperature control from the housing.
NOTE: You may have to remove the wires attached to the
control. Take note as to which wire is on which spade terminal.
STEP 4 - Pull out gently from cabinet.
STEP 5 Each 1/4 turn of the calibration screw is equal to
approximately 2 degrees F. Do not make more than 3/4 turn.
After making adjustment, measure temperature during three
cycles before adjusting again.
NOTE: Only adjust the screw (small flathead) on the face of
the control (next to the cam). See Figure 3.
STEP 6 - Make sure to reconnect the wires to the proper
spade terminal when reinstalling.
Follow the Altitude Correction Table to the right.
