I replaced my defrost timer a few weeks ago, as the original timer was sticking in defrost mode. I confirmed that the timer was hooked up correctly as there is an extra black wire which I installed on terminal #1. The new timer worked great for 5 or 6 days, and then stuck again in defrost mode. When I advance the timer manually with a screwdriver, it works okay for a few days, then sticks again in defrost mode. Do you think I might have gotten a defective timer as a replacement , and buy another one? I'm thinking the defrost bi-metal (part# 4387503) might be causing the problem. Your help in this matter is greatly appreciated.
ANSWER Hello Jim. Black wire is in wrong location on the timer. For cumulative run timer
push slotted loose timer
motor lead over & all the
way down terminal
number 2 with wire
toward timer motor.
