Maytag F23

Maytag error code F23 indicates: Maytag Maxima MEDB Steam & Extra Power Tumble Dryer: Exhaust outlet thermistor short circuit F23; control board detects zero resistance across sensor lines and terminates cycle..

The primary root cause for Maytag code F23 is: On Maytag dryers (Maytag Commercial Technology heavy-duty direct drive chassis and industrial-grade relays): Pinched thermistor harness wires shorted to metal blower housing, or internal breakdown of thermistor bead semiconductor material..

To resolve error code F23: Inspect wiring harness for crushed insulation against chassis. Unplug thermistor and measure resistance: replace sensor if resistance reads <500 Ω. Rotate cycle dial 1 full turn counter-clockwise, then 3 clicks right, 1 click left, 1 click right. All status LEDs illuminate; press Start to begin diagnostics.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Maytag code F23 persists, the physical component causing On Maytag dryers (Maytag Commercial Technology heavy-duty direct drive chassis and industrial-grade relays): Pinched thermistor harness wires shorted to metal blower housing, or internal breakdown of thermistor bead semiconductor material. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
