Description

This mechanical timer controls your refrigerator's automatic defrost cycle. Replacing a worn or stuck timer restores routine defrosting to prevent frost buildup and helps the appliance maintain steady, reliable cooling. What it does:

• Alternates power between the cooling circuit and the defrost heater at set intervals
• Helps clear frost from the evaporator so air can circulate properly
• Common failure symptoms: heavy frost on the back wall/evaporator, fresh-food section too warm, unit never defrosts or gets stuck in defrost, compressor running excessively

What's included:

• 1 defrost timer

Install notes:

• Disconnect power before servicing
• Access the timer (often in the control housing or rear service area); note wire positions with a photo
• Transfer wires one at a time to matching terminals and snap the timer into the bracket/original orientation
• Restore power and monitor through a cooling/defrost cycle to normal operation
