Amana Oven: not heating

Professional Repair Guide

What is this symptom?

Is your Amana oven not heating properly? You may notice that it powers on but fails to generate heat during Bake or Broil modes. The temperature might not rise at all, rise slowly, or stop heating altogether. Common issues include a burned-out heating element, a weak oven igniter, or incorrect control settings like Delayed Start or Demo Mode. Find out how to troubleshoot and fix these problems effectively.

Urgency: Medium

Important Tips for Amana Models

  • Official Amana guidance notes that Demo Mode disables oven operation and Delayed Start settings can make it appear the oven is not heating until the scheduled time.

Possible Causes

Bake heating element burned out (electric ovens) or not receiving power

How to Identify: Oven does not heat in Bake, may still heat in Broil. Visual signs: blistering, cracks, holes, or portions not glowing (if visible. Confirm with multimeter: no continuity through the bake element.

Part: Bake element

Weak or failed oven igniter (gas ovens) causing no ignition or delayed ignition

How to Identify: When Bake is turned on, igniter may not glow, may glow dimly, or burner never lights. You may smell gas without ignition in some cases. If igniter glows but burner doesn’t light within ~60–90 seconds, igniter may be weak.

Part: Bake igniter / glow bar igniter

Oven control board / relay board not sending voltage to bake element or igniter

How to Identify: Bake element/igniter tests good but still no heat. May hear relays clicking with no heating. Visual board damage (burn marks can be present. Confirm by checking for proper voltage output to element/igniter using wiring diagram and multimeter.

Part: Oven control board (ERC) / relay board

Control settings preventing heating (Delayed Start or Demo Mode enabled)

How to Identify: Oven appears to accept settings but does not begin heating. Delayed Start may show a start time; Demo Mode often displays a feature presentation and prevents operation. Cancel delayed start and disable demo mode per owner’s manual.

Part: User control settings / electronic control

Oven temperature sensor (thermistor) out of range causing incorrect heating behavior

How to Identify: Oven may heat erratically, stop heating early, or display temperature errors depending on model. Sensor can be tested for resistance per service manual specs; replacing the sensor is a common repair part for Amana ranges.

Part: Oven temperature sensor / thermistor

Thermal fuse blown (some models) cutting power to oven heating circuit

How to Identify: Oven will not heat at all; sometimes other oven functions may be limited depending on wiring. Fuse tests open (no continuity. Often occurs after overheating or airflow restrictions.

Part: Thermal fuse / cutoff

DIY Solutions

Cancel Delayed Start and disable Demo Mode (official Amana fix)

Easy 2-10 minutes
  1. Check the control panel for any Delayed Start settings; cancel the delayed bake and start a normal Bake cycle.
  2. Check whether Demo Mode is enabled (some models show a feature/demo presentation and will not heat). Disable Demo Mode following the model’s owner’s manual instructions.
  3. Test Bake again and confirm the temperature rises.
⚠️ Safety First: No disassembly required; safe for homeowners.

Inspect and test the bake element (electric ovens) and replace if failed

Moderate 30-60 minutes
Tools Needed: Screwdriver or nut driver, Multimeter, Work gloves
  1. Turn off power at the circuit breaker before servicing.
  2. Visually inspect the bake element for cracks, blisters, or holes.
  3. Remove mounting screws and gently pull the element forward to access wires; disconnect terminals.
  4. Test the element for continuity with a multimeter; if open/no continuity, replace the bake element.
  5. Reconnect wires securely, reinstall the element, restore power, and test Bake.
⚠️ Safety First: Always turn off power at the breaker to prevent electric shock.

Replace a weak or failed oven igniter (gas ovens)

Advanced 45-90 minutes
Tools Needed: Screwdriver or nut driver, Work gloves, Optional: multimeter/amp clamp
  1. Shut off power to the range at the breaker and turn off the gas supply valve.
  2. Remove oven racks and the bottom panel to access the bake burner and igniter.
  3. Disconnect the igniter connector (or cut/splice using a ceramic wire-nut kit if required by the replacement part instructions).
  4. Remove mounting screws, replace the igniter with the correct model-matched part, and reassemble.
  5. Restore gas and power, then test that the burner ignites promptly in Bake.
⚠️ Safety First: Turn off gas and power before servicing.

Quick control reset (breaker reset) for control glitches

Easy 5-10 minutes
  1. Turn off the oven circuit breaker for 1–2 minutes.
  2. Turn the breaker back on.
  3. Set the clock (if required) and test Bake again.
⚠️ Safety First: If the breaker trips again immediately, stop and call a professional.

Estimated Cost: $250 - $800 (parts + labor, varies widely by model)

Replace oven temperature sensor and calibrate/test heating performance

Estimated Cost: $150 - $350 (parts + labor)

Gas safety valve testing/replacement (rare cause)

Estimated Cost: $250 - $600 (parts + labor)

When to Call a Professional

You smell gas when attempting to bake and the burner does not ignite.
The breaker trips repeatedly when Bake is started or there are signs of burnt wiring.
Bake element/igniter has continuity (or igniter glows strongly) but the oven still won’t heat—likely control board/relay diagnostics are needed.
You are not comfortable working around gas connections or performing electrical voltage tests.

Preventive Maintenance

  • Keep the oven interior and burner area (gas models) free of heavy grease buildup to reduce overheating and ignition issues.: Ignition delays, overheating that can contribute to thermal fuse trips, and uneven heating
    Frequency: monthly or as needed
  • Avoid lining the oven bottom with foil unless the manual explicitly allows it; keep vents clear for airflow.: Overheating, poor airflow, and potential thermal cutoffs
    Frequency: always
