ing side panels.
Access to all internal plumbing and electrical assemblies
is from the right side. The right-side panel is removed by
removing the bottom screws from panel.

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 at external circuit breaker.
2. Disconnect all three wires from timer terminals.
3. Connect an ohmmeter between terminals 21 and 22.
4. Rotate timer dial beyond the “0 - Minute” point (any
setting) to obtain a reading of zero ohms on the ohm-
meter. If zero ohm reading cannot be obtained, timer
contacts are defective and the timer must be replaced.
5. Move ohmmeter leads to terminals 21 and 24.
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. Move ohmmeter leads to terminals 11 and 12.
8. Rotate the timer dial to the “CONSTANT STEAM” po-
sition. If zero ohm reading cannot be obtained, the
timer is defective and must be replaced.
9. Remove ohmmeter and replace all three leads on
timer terminals.
