Frigidaire Oven: fan pulsing on and off

Professional Repair Guide

What is this symptom?

If your Frigidaire oven's fan is pulsing on and off during use, you might be experiencing a common issue. This behavior occurs when the internal fan does not run continuously but instead activates intermittently during heating or cooling cycles. Understanding whether this is normal operation or a sign of a malfunction can help you address the concern effectively.

Urgency: Low

Important Tips for Frigidaire Models

  • Official guidance states the fan cycling on/off during use and cooling is normal to regulate temperature.

Possible Causes

Normal operation of convection or cooling fan cycling based on temperature control algorithms

How to Identify: Fan runs on/off during preheat, cooking, or cooling as part of normal thermal management; no unusual noises or extended run times

Part: Convection or cooling fan control

Temperature sensor sending incorrect readings causing extended or irregular fan cycling

How to Identify: Fan runs excessively or at odd intervals, oven warm even after cooling, temperature control inaccuracies

Part: Oven temperature sensor (thermostat)

DIY Solutions

Observe Normal Fan Cycling Behavior

Easy No time; observational
  1. Use oven in normal cooking modes and note fan operation patterns
  2. Compare fan activity to baking stages (preheat, cooking, cool-down)
⚠️ Safety First: No internal access required

Reset Oven Control to Clear Minor Glitches

Easy 10 minutes
Tools Needed: Access to circuit breaker or power cord
  1. Turn off the oven’s circuit breaker or unplug it
