Magic Chef Control Board

The Defrost Control Board is an OEM part for Whirlpool refrigerators. This board manages the defrost cycle by controlling the defrost heater and monitoring the freezer's temperature. 

Causes of a bad defrost control board can include electrical issues, wear from continuous use, or damage from power surges.  

Symptoms of a bad defrost control board include:

• Excessive frost buildup in the freezer compartment
• The refrigerator not cooling properly
• The defrost heater not activating
• The refrigerator running continuously without cycling off

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

This refrigerator defrost timer automatically starts and ends the defrost cycle to melt frost from the evaporator coils. Replacing a failed timer restores consistent cooling performance and helps prevent frost buildup that can restrict airflow.

• Controls the timed switch between cooling and defrost to keep evaporator coils clear of frost
• Common symptoms of failure: heavy frost on the evaporator or back panel, fresh food section too warm, unit runs constantly, or won't resume cooling after defrost
• Restores proper frost removal and airflow for stable temperatures
• Designed to match the original timer's function and wiring connections for applicable models

• Disconnect power before servicing; wear cut-resistant gloves
• Access location varies by model—often in the fresh food control housing or rear machine compartment
• Photograph/label wire positions and transfer them to the matching terminals on the new timer
• Reuse original mounting hardware and install in the same orientation as the original

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

This electronic control board is the command center for your oven/range. It interprets keypad inputs, switches bake/broil circuits, and regulates temperature via the sensor to restore responsive controls, accurate timing, and consistent heating when the original board fails.

• Receives user input and drives the clock/timer and display
• Controls power to bake and broil relays or igniters based on sensor feedback
• Regulates oven temperature and cycle timing
• Stores/displays fault codes to help diagnose issues
• Typical symptoms: no heat or intermittent heat, unresponsive controls or dead display, erratic temperatures, beeping or error codes

• Disconnect power at the breaker before servicing; verify no voltage is present
• Handle the new board with ESD care; avoid touching circuitry and components
• Move connectors one at a time to matching terminals; reuse existing mounting hardware and panel components as your model requires
• After reassembly, restore power, set the clock, and run a test preheat; for diagnostics or temperature calibration if needed

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

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.

This timer is the electromechanical control that sequences wash/dry cycles and timed functions. It replaces a failed cycle timer so the appliance can advance through settings and control timed operations reliably. What it does:

• Rotates through timed cycles and engages switch contacts to power motors, heaters, and valves in sequence
• Restores timed control when the original timer fails to advance or get stuck
• Common symptom: appliance does not advance through cycles or stays on a single cycle
• Common symptom: selector changes have no effect or certain functions do not receive power

• Disconnect power to the appliance before starting any repair to avoid shock
• Handle electrical connectors gently and note wire locations or take a photo before disconnecting
• Verify this part number matches the service diagram for your exact model before installation
