This procedure contains information and instructions for inspecting and repairing the Mobile
Warming Cabinet. Refer to WP 0038 00 for repair parts information.
Unplug the power cord before performing any maintenance on the warming
cabinet.
INSPECT
Inspect the door gaskets and door seals for signs of wear or damage.
TEST
Cabinet: If the warming oven is not heating at all, check that the warming oven power cord is
connected properly, the master switch is On and the circuit breaker at the Power Distribution
Panel is On. Disconnect the power cord and remove the Module using the procedure in the
following section. Temporarily connect the power cord and check for 115 VAC at the power
switch. If voltage is present on both sides of the switch the module requires replacement.
Replace the power switch if required.
If the temperature in the warming oven is erratic or cannot be controlled, check the voltage at
the thermostat. Rotate the thermostat control while checking voltage. A smooth change in
voltage over the range of the thermostat should be noted. Replace the thermostat if necessary.
If the warming oven is operating normally but the indicator lamps are not lit, check voltage at the
terminal block and replace the indicator lights if necessary.
