Admiral Refrigerator Defrost Timer, Adaptive Defrost Control

This defrost timer controls when your refrigerator or freezer enters and exits the automatic defrost cycle to clear frost from the evaporator coils. Replacing a failed timer restores reliable defrosting to help maintain airflow, cooling performance, and stable temperatures.

• Advances on a timed schedule to initiate and end the defrost cycle
• Sends power to the defrost heater during defrost, then returns the system to cooling
• Helps prevent heavy frost buildup that restricts airflow and cooling
• Common symptoms of a bad timer: unit not defrosting or warming over time, heavy ice on the evaporator/cover, stuck running or stuck in defrost, or a timer that won't advance

• Disconnect power before servicing
• Access the timer (commonly in the control housing or machine compartment)
• Note/photograph wire positions and move leads one at a time to the new timer; mount securely
• Restore power and monitor for proper cycling; some models allow using the timer's advance slot to start a test defrost

This defrost timer controls the automatic defrost cycle in select refrigerators and freezers, switching between cooling and defrost to clear frost on the evaporator. It helps maintain stable temperatures and prevents heavy ice buildup and long run times. What it does:

• Alternates the system between cooling and defrost on a timed schedule
• Sends power to the defrost heater during defrost, then returns power to the compressor and fans
• Failure can cause heavy frost on the evaporator/back freezer wall
• May lead to warmer temperatures, constant running, short cycling, or no-cool if stuck in defrost

• 1 defrost timer

• Disconnect power before servicing
• Access location varies by model
• Note wire positions and transfer them one at a time to the new timer
• Mount securely in the same orientation as the original and verify normal cycling after power is restored

The defrost timer controls your refrigerator's automatic defrost cycle, periodically pausing cooling to power the defrost heater. Replacing a faulty timer restores proper defrosting to help prevent frost buildup, temperature swings, and excessive run time.

• Advances the system between cooling and defrost at set intervals
• Sends power to the defrost heater, then returns the unit to cooling
• Failure may cause heavy frost on evaporator coils and weak airflow
• Fresh food section may run warm while the freezer ices over
• Unit may run constantly, never defrost, or get stuck in defrost

• Disconnect power before servicing
• Location varies by model; access the timer (often in the control housing or rear compartment), note wire positions, and transfer one at a time
• Mount and secure the timer as originally installed; reuse existing bracket/fasteners
• After reassembly, restore power and verify the unit advances through cooling and defrost

This electronic control board manages the appliance's functions and user interface, restoring normal operation when the original board fails. It replaces a faulty control module to help re-enable cycles, settings, and display feedback. What it does:

• Receives input from the control panel and sensors to run timed cycles and selected options
• Controls power delivery, timers, and cycle sequencing for proper operation
• Can cause error codes, unresponsive buttons, or intermittent operation if damaged

• One electronic control board (main control board) as shown

• Disconnect power before removing or installing the control board to avoid shock or damage
• Handle the board carefully; avoid touching circuitry and use anti-static precautions when possible
• Verify the board mounting, wiring harness connections, and connectors seat fully during installation

Defrost timer that advances the refrigerator's defrost cycle at roughly six-hour intervals to help prevent excessive frost buildup and keep cooling consistent. Replaces a failed timer to restore regular defrost scheduling. What it does:

• Advances the defrost cycle so the heater can melt frost from the evaporator on a timed schedule.
• Helps prevent heavy ice buildup that can reduce airflow and cooling performance.
• Common symptoms of a failing timer: excessive frost or ice accumulation, compressor running constantly, or inconsistent temperatures.
• Works with mechanical defrost systems to alternate between cooling and defrost intervals.

• Disconnect power to the appliance before servicing to avoid electrical shock.
• Handle connectors and wiring carefully; ensure all terminals are fully seated.
• Mounting hardware and connector types can vary by model—retain original fasteners and note wiring positions before removal.

Kit, defrost timer (230 vac)

This mechanical rotary defrost timer controls and advances the refrigerator's defrost cycle so the evaporator periodically melts frost buildup, helping restore normal cooling. It replaces a worn or stuck timer to return automatic defrost operation. What it does

• Advances the fridge's defrost cycle on a set schedule so the evaporator heats and melts frost
• Stops the compressor during defrost so frost is removed without cooling loss
• Common symptom: excessive frost buildup on evaporator or freezer compartment
• Common symptom: refrigerator or freezer runs constantly or does not cool properly

• One defrost timer (rotary)

• Disconnect power to the appliance before starting any repair
• Locate timer (control panel, kick plate, or rear panel depending on model) and note original orientation before removal
• Remove mounting screws and electrical connector(s); install new timer in the same position and reconnect wiring
