Maytag Refrigerator: ice buildup

Professional Repair Guide

What is this symptom?

Experiencing ice buildup in your Maytag refrigerator can be frustrating. Excess frost may accumulate in the freezer or refrigerator compartments, obstructing airflow and affecting performance. This issue often arises from a faulty defrost system, door leaks, or blocked vents. Identifying the cause early can help prevent further complications and ensure your appliance runs smoothly.

Urgency: Medium

Important Tips for Maytag Models

  • Maytag refrigerators recommend minimizing door openings, ensuring proper seals, and unblocking air vents to reduce frost; use Energy Saver feature off to engage moisture reduction heater on some models.

Possible Causes

Faulty or inefficient defrost system

How to Identify: Excess ice on evaporator coils or freezer walls; defrost cycle not running; thermostat or heater shows no continuity with a multimeter.

Part: Defrost heater, defrost thermostat, defrost control board/timer

Door gasket/leakage allowing moist air entry

How to Identify: Warm moist air enters; visible frost around door edges; paper/dollar-bill test shows weak seal.

Part: Door gasket/seal

Blocked airflow inside freezer/refrigerator

How to Identify: Ice often builds near vents; overpacked compartments; evaporator fan not circulating properly.

Part: Air vents/evaporator fan

Frequent door opening or high humidity environment

How to Identify: Symptom follows heavy use/door opening; more frost when humidity is high.

Part: Environmental conditions

Temperature settings too low

How to Identify: Freezer set excessively cold; adjusting temp reduces ice over time.

Part: Temperature control thermostat

Clogged defrost drain

How to Identify: Ice at bottom of freezer or blocking drain; water pooling after defrost.

Part: Defrost drain
