REPLACING ELECTROMECHANICAL TIMERS
The current universal defrost timer kit (Part No. 482493) will work as a service replacement in units
where the timer motor circuit is routed through the run winding of the compressor to neutral and in
units where the timer motor circuit is routed directly to neutral. This universal defrost timer kit will
replace all 8, 10, 12 and 24-hour timers. The timer in this kit has a black jumper wire lead that must be
connected to a terminal on the timer prior to installing it in the unit. The replacement timer terminals
are numbered. ALWAYS CONNECT THE CABINET LEADS TO THE SAME NUMBERED TERMI-
NALS AS THE DEFECTIVE TIMER. Check the wiring diagram label on the back of the cabinet, or on
the Tech Sheet, located in the unit compartment.
• If the wiring schematic looks like the one below, the timer motor circuit is routed directly to
neutral.
• The black jumper wire on the timer should be pressed onto Terminal 1.
• If the wiring schematic looks like the one below, the timer motor circuit is routed through the
compressor motor to neutral.
• The black jumper wire on the timer should be pressed onto Terminal 2.
