Timer Contacts
Defective timer contacts will result in failure of cooker compartment to operate. When this
occurs, remove the side panel and proceed as follows:
1. Turn off power to the cooker at external circuit breaker.
2. Disconnect all three 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 three 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.
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 240 Volts.
2. Turn on power to the steamer.
