Step1: Disconnect electrical power and allow the equipment to cool before servicing the control compartment.
Step2: Remove the access panel to reach the thermostat body, capillary tube, and sensing bulb assembly.
Step3: Carefully disconnect wiring terminals and gently remove the old thermostat without bending or kinking the capillary tube.
Step4: Mount the new thermostat in the same position and route the sensing bulb in the original location for accurate temperature control.
Step5: Reconnect wiring securely, reassemble the unit, restore power, and verify proper temperature cycling during operation.
