Maytag E2

Maytag error code E2 indicates: Maytag PowerCold MFI French Door Refrigerator: Freezer evaporator coil thermistor fault E2; frost accumulates on back wall and cooling performance degrades..

The primary root cause for Maytag code E2 is: On Maytag refrigerators (Maytag Commercial Technology heavy-duty direct drive chassis and industrial-grade relays): Defrost thermistor clipped to evaporator tubing open circuit, shorted, or water intrusion causing ice expansion damage..

To resolve error code E2: Remove freezer back panel. Measure evaporator thermistor resistance: nominal 7.9 kΩ at 0°C (32°F) or 22.0 kΩ at -18°C (0°F). Replace thermistor if open or short. Press and hold Max Cool and Temp Down buttons simultaneously for 3 seconds until audible confirmation chime sounds to clear diagnostic codes.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Maytag code E2 persists, the physical component causing On Maytag refrigerators (Maytag Commercial Technology heavy-duty direct drive chassis and industrial-grade relays): Defrost thermistor clipped to evaporator tubing open circuit, shorted, or water intrusion causing ice expansion damage. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
