Heat Loss:
Inspect the magnetic door gasket to make certain it seals against the
cabinet at all points. Place a sheet of paper between the door and
cabinet; then close the door. There should be some resistance when
removing the paper
The vinyl door gasket can be heated with a hot air gun and pulled
slightly away from the door frame to retain its original shape. This
procedure can be used to help secure proper door sealing
The door can be adjusted by loosening the screws that mount the door
hinge to the door.
No Heat:
1. Be sure line voltage is the same as shown on the nameplate.
2. Check switches and electrical connections.
3. Check heater resistance, which should be 41 ohms per heater coil.
Loss of Cooling Efficiency:
The heat exchange coils of the compressor must be kept clean and free
of dust. Periodic inspection and cleaning is important.
Remove mounting screws that fasten the control compartment cover to the
top of the chamber. Lift cover off the cabinet to gain access to electrical
components such as switches, pilot lights, heater, and thermostats.
Pilot Light Replacement:
1. Remove clip that fastens the pilot light to rear of panel.
2. Tag wires for identification; then disconnect.
3. Remove pilot light and replace in reverse order.
