Frigidaire Refrigerator Defrost Timer Parts — Models & Compatibility

If you're seeing heavy frost buildup in your Frigidaire freezer or noticing warm sections in the fridge compartment, there's a good chance your defrost timer has stopped cycling properly. This hub covers the 241705102 defrost timer — a critical component that works with over 100 Frigidaire, Electrolux, Kenmore, and Crosley refrigerator models. When this timer fails, it prevents the defrost cycle from kicking in, leading to ice accumulation that blocks airflow and ruins temperature regulation.

Is This the Right Part for Your Model?

Check your refrigerator's model number before ordering. You'll typically find it on a sticker inside the fresh food compartment, often on the left or right wall near the top. Match your full model number against our compatibility list below — this timer works with FFTR, FFHI, FFHT series and several Kenmore 253 series models. The part number 241705102 replaces older versions AP5986785, PS11726371, and 4378243.

About This Replacement Part

The defrost timer controls when your refrigerator switches from cooling mode to defrost mode, typically cycling every 8-10 hours depending on compressor runtime. When it fails — usually due to motor wear or electrical contact degradation — the system gets stuck in cooling mode. You'll notice ice sheets forming on the evaporator coils, frost creeping into food storage areas, and eventually warm spots as blocked airflow prevents proper circulation. Some owners report their unit won't run at all, though interior lights still work, which indicates the timer locked up completely. Replacing this part restores normal defrost cycling and prevents the compressor from overworking.

Common Signs You Need This Part

• Heavy frost or ice buildup in freezer compartment
• Warm temperatures in refrigerator sections despite running compressor
• Unit cycles on but never enters defrost mode
• Refrigerator won't run but lights and controls still function
• Excessive frost around evaporator fan area

Installation Overview

Always disconnect power at the breaker before starting any repair work. The defrost timer is typically located behind the lower kickplate panel or inside the control housing near the temperature controls, depending on your model. You'll need to unplug the wire harness, remove mounting screws, and transfer connections to the new timer. Follow your specific model's service manual for exact location and wiring configuration — some models have different wire colors and terminal arrangements.

Compatible Model Series

This defrost timer works across multiple Frigidaire series including top-freezer models (FFTR), built-in refrigerators (FFHI), and counter-depth units (FFHT). It's also compatible with rebranded Crosley (CRTE) models and select Kenmore 253 series refrigerators manufactured by Frigidaire. Check the full compatibility list below to confirm your model.
