Symptom / Description

FAULT

Frigidaire Professional / Gallery Smudge-Proof Oven: Electronic control board over-temperature F104; thermal sensor on main PCB measures excessive temperature (> 85°C).

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Frigidaire (Frigidaire Professional / Gallery Smudge-Proof Oven) models: Cooling fan failure during extended high-temperature bake or pyrolytic cycle, blocked top ventilation slits in cabinet, or deteriorated cavity insulation.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Check kitchen installation clearances (minimum 50mm rear air gap). Ensure cabinet vents are clear of obstructions. Verify cooling blower operation. Press and hold Cancel / Drain for 3 seconds, or cycle the control lock for 5 seconds to clear persistent memory fault log.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: Frigidaire F104

FAQ TREE

What does error code F104 mean on a Frigidaire appliance?

Frigidaire error code F104 indicates: Frigidaire Professional / Gallery Smudge-Proof Oven: Electronic control board over-temperature F104; thermal sensor on main PCB measures excessive temperature (> 85°C)..

What is the root cause of Frigidaire error code F104?

The primary root cause for Frigidaire code F104 is: On Frigidaire (Frigidaire Professional / Gallery Smudge-Proof Oven) models: Cooling fan failure during extended high-temperature bake or pyrolytic cycle, blocked top ventilation slits in cabinet, or deteriorated cavity insulation..

How do I fix or resolve Frigidaire error code F104?

To resolve error code F104: Check kitchen installation clearances (minimum 50mm rear air gap). Ensure cabinet vents are clear of obstructions. Verify cooling blower operation. Press and hold Cancel / Drain for 3 seconds, or cycle the control lock for 5 seconds to clear persistent memory fault log.

Is it safe to clear Frigidaire error code F104 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Frigidaire code F104 persists, the physical component causing On Frigidaire (Frigidaire Professional / Gallery Smudge-Proof Oven) models: Cooling fan failure during extended high-temperature bake or pyrolytic cycle, blocked top ventilation slits in cabinet, or deteriorated cavity insulation. must be inspected or replaced.

How do I test electrical resistance for Frigidaire code F104 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

What safety protocol must be followed before servicing Frigidaire code F104?

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.
