Whirlpool Refrigerator / Freezer P1

Whirlpool error code P1 indicates: Whirlpool 6th Sense Dual-Cool & Total NoFrost Refrigerator: Diagnostic code P1 indicates delicatessen pantry drawer temperature sensor circuit open or shorted..

The primary root cause for Whirlpool code P1 is: On Whirlpool refrigerators (Whirlpool 6th Sense algorithms and WAVE / L1373 electronic platform): Severed sensor harness during drawer removal, moisture ingress in probe connector, or failed NTC bead (nominal 2.7 kΩ at 25°C)..

To resolve error code P1: Disconnect power. Remove pantry drawer and unclip sensor cover. Measure sensor resistance (2.7 kΩ at 25°C). Inspect wiring harness pin contacts. Replace pantry thermistor if open. Press and hold the Filter Reset or Alarm Silence touch pad for 5 seconds until the confirmation chime sounds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Whirlpool code P1 persists, the physical component causing On Whirlpool refrigerators (Whirlpool 6th Sense algorithms and WAVE / L1373 electronic platform): Severed sensor harness during drawer removal, moisture ingress in probe connector, or failed NTC bead (nominal 2.7 kΩ at 25°C). 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.
