Maytag F25

Maytag error code F25 indicates: Maytag MEC Speed Heat Radiant & Induction Cooktop: Cooking zone element temperature sensor fault F25; designated cooking zone is shut down to prevent ceramic glass overheating..

The primary root cause for Maytag code F25 is: On Maytag cooktops (Maytag Commercial Technology heavy-duty direct drive chassis and industrial-grade relays): NTC thermistor bead in center of induction coil or radiant element open circuit (>500 kΩ) or shorted to coil chassis..

To resolve error code F25: Unplug cooktop. Disconnect sensor connector from power board. Measure coil NTC resistance: nominal 100 kΩ or 10 kΩ at 25°C (77°F). Replace coil sensor if open/short. Switch off double-pole 240V supply breaker for 3 minutes. Clean ceramic surface and restore power to recalibrate touch controls.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Maytag code F25 persists, the physical component causing On Maytag cooktops (Maytag Commercial Technology heavy-duty direct drive chassis and industrial-grade relays): NTC thermistor bead in center of induction coil or radiant element open circuit (>500 kΩ) or shorted to coil chassis. 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.
