SWITCH REPLACEMENT - (FAN SWITCH UPDATE)
INSTALLATION OF DOUBLE POLE FAN SWITCH #369260 IN PLACE OF SINGLE POLE
FAN SWITCH #350705
NOTE:
This change is not necessary for proper operation of oven nor is it
permissible to change under warranty. Should be changed only at
customer's request and their agreement to pay your bill.
ADVANTAGE: Allows time/temp. display, in older models, to operate same as current
production models. Also allows locked time/temp. display (caused by
voltage surge, interruption or spike) to be reset by fan switch rather than
circuit breaker.
IDENTIFICATION: To determine which fan switch you have, observe if temperature displays
stays on during cooling down. If it stays on , you have the single pole
switch. If it goes out as soon as fan switch is turned off you have the double
pole switch.
REPLACEMENT: Replace single pole switch # 350705.
Install double pole switch # 369260.
Disconnect lead indicated by # in proper diagram and reroute as shown.
Install jumper lead indicated by * in proper diagram.
Reapply all other leads as removed.
