Frigidaire Oven: not maintaining temperature

Possible Causes

Faulty temperature sensor (oven sensor)

How to Identify: Use an oven thermometer to verify actual internal temp vs set temp; sensor readings out of spec or resistance values incorrect on multimeter.

Part: Oven temperature sensor

Weak or failing igniter (gas models)

How to Identify: On gas models, oven temp drops >40°F before reignition; igniter glows weakly or not at all; measured current may be low.

Part: Oven igniter

Faulty control board

How to Identify: Voltage to heating elements/igniters cut off prematurely/erratically; visual signs of shorts or burnt components.

Part: Oven main control board

Damaged door seal or latch

How to Identify: Heat escaping from oven; poor door closure; visually worn rubber gasket or misaligned latch.

Part: Door gasket/latch assembly

DIY Solutions

Calibrate Oven Temperature

Moderate 15–30 minutes

Tools Needed: oven thermometer

1. Place oven thermometer inside oven and preheat to a set temp.
2. Compare actual temp to set temp after cycling.
3. Adjust calibration per the oven’s manual up or down until readings align.

⚠️ Safety First: Ensure oven is off when adjusting controls.

Visual Inspect and Test Heating Elements

Moderate 20–40 minutes

Tools Needed: multimeter

1. Turn off power to oven.
2. Inspect elements for visible burns or breaks.
3. Test continuity with multimeter; replace if open.
4. Reinstall and test oven heat retention.

⚠️ Safety First: Disconnect power before working on electrical components.

Check Door Seal and Latch

Easy 10–20 minutes

Tools Needed: none

1. Inspect door gasket for cracks or wear.
2. Manually close door to test snug fit.
3. Replace gasket or tighten/adjust latch if heat is escaping.

⚠️ Safety First: Be cautious of pinch points in door hinge area.

When to Call a Professional

Oven fails to heat at all after DIY checks

Gas smell or suspected gas line issues

Control board appears damaged or after multiple component failures

Electrical wiring issues present

Igniter testing indicates failure

Preventive Maintenance

• Regularly check and clean door gasket: Heat loss and improves temp maintenance
  Frequency: monthly
• Use an oven thermometer periodically: unnoticed temperature drift and identifies need for calibration
  Frequency: every 3 months
