60-MINUTE TIMER
Timer Contacts
Defective timer contacts will result in failure of either cooker compartment to operate. When
this occurs, remove the control pan and proceed as follows:
1. Turn off power to the cooker at external circuit breaker.
2. Disconnect all five wires from timer terminals.
3. Connect an ohmmeter between terminals 1 and 3.
4. Rotate timer dial beyond the “0-Minute” point (any setting) to obtain a reading of zero ohms
on the ohmmeter. If zero ohm reading cannot be obtained, timer contacts are defective and
the timer must be replaced.
5. Move ohmmeter leads to terminals 1 and 4.
6. Rotate timer dial to “0-Minute” position (an audible click indicates correct position). If zero
ohm reading cannot be obtained, the timer is defective and must be replaced.
7. Remove ohmmeter and replace all five leads on timer terminals.
Timer Motor
A defective timer motor will cause continuous operation in the TIME mode, with the timer dial
failing to return to the “0-Minute” position. Since thermostatic switch failure can cause the same
symptom, fault must first be isolated to the timer by testing the thermostat.
To confirm timer motor condition, proceed as follows:
1. Carefully check motor wire leads and tighten loose connections.
WARNING: Use care while working with control panel. Terminals
carry 120 Volts.
2. Turn on power to the steamer.
3. Set timer dial (any setting beyond “0-Minute”). If operation is correct, the motor will turn the
dial toward “0-Minute”. If the motor fails to operate, it is defective and the entire timer must
be replaced.
4. Shut off power to the cooker.
