Frigidaire Oven Won’t Heat | Fast Fix Guide

Nothing slows dinner like an oven that stays cold. This step-by-step guide walks through the quickest checks first, then moves to simple tests you can do with basic tools. You’ll see what to look for on both electric and gas models, learn the common failure parts, and get safe ways to confirm each one before you buy anything.

Frigidaire Oven Not Heating — Quick Checks

Start with the easy wins. Many “no heat” calls trace back to a tripped breaker, a mode setting, or a door/lock state that blocks heat. Run through these in order.

Symptom	Likely Cause	What To Check
No heat on Bake or Broil (electric)	Half power, blown element, bad sensor, failed control	Confirm 240V across L1–L2 at the range; inspect bake/broil element for breaks; ohm the temperature probe; test output from the control
No heat (gas)	Weak glow igniter, closed gas valve, open safety thermostat	Watch the igniter: should glow bright and draw ~3.2–3.6 A; verify gas supply; check safety thermostats for continuity
Numbers change but no flame/heat	Sabbath/child lock, delayed start, control lock	Turn off special modes; clear delayed start; cancel lock states
Heat on Broil only	Open bake element or relay	Inspect and meter the bake element; check control board bake relay output
Stuck around 100–150°F	Open sensor circuit or weak igniter	Probe should measure ~1080–1100 Ω at room temp; on gas, verify igniter amperage
After self-clean, no heat	Tripped high-limit, open wiring at rear, blown element	Check rear safety thermostats/thermal cutouts for continuity; inspect harness and elements

Safety First

Unplug the range or switch off the breaker before removing panels. For gas models, close the gas shutoff. Use an insulated multimeter and avoid exposed live parts. If a step calls for a live test and you’re not comfortable, skip to the next section or call a technician.

Power And Mode Checks (Both Types)

Verify Full Power On Electric Models

Ranges need two hot legs that add up to 240V. A tripped half-breaker lets lights and the clock run on 120V, but heating stays off. Reset the double-pole breaker. If it trips again, stop and have the circuit inspected.

Make Sure Special Modes Aren’t Blocking Heat

Some models can enter modes that mute beeps or limit control response. If the display shows “Sb” or a similar icon, exit the Sabbath feature using the key combo in your manual. You can also run a quick test: set a basic Bake, wait two minutes, and watch for rising temperature. If nothing changes, clear any delayed start or lock states and try again.

Electric Models: Fast Tests That Pinpoint The Fault

1) Inspect The Bake And Broil Elements

Pull the oven racks and shine a light along each element. A blister, split, or burn mark usually points to an open element. If you see damage, disconnect power and meter it end-to-end. A healthy element reads low resistance (often 10–40 Ω depending on model). Any open reading means replacement.

2) Check The Temperature Probe (RTD)

Find the thin metal probe on the rear wall inside the cavity. Remove its two screws and gently pull the connector forward. With the harness separated and the probe at room temp, measure resistance across the two pins. You should see roughly 1080–1100 Ω near 70°F and smooth increases with heat. Out-of-range or jumpy readings point to a bad probe.

3) Confirm The Control Sends Power

With panels removed and power restored, a trained person can check for 240V leaving the board to the bake circuit when Bake is commanded. No output with a known-good element and probe suggests a failed relay or control. Cut power again before reassembling.

Gas Models: Quick Way To Separate Igniter From Valve Issues

1) Watch The Glow Igniter

Set Bake and look through the lower panel for a bright, even glow. A weak bar that glows dull or takes a long time to light the burner is a classic sign the igniter can’t pull enough current to open the valve. Many Frigidaire ovens use flat ceramic igniters that should draw roughly 3.2–3.6 amps once up to temperature. If it glows forever without flame, the igniter is the first suspect.

2) Confirm Gas Supply And Valve State

Make sure the manual shutoff is parallel with the line. If the cooktop burners light normally, supply is present. No burner flame anywhere likely means the valve is closed upstream or there’s a supply issue that needs a pro.

3) Check Safety Thermostats

After a high-heat event, rear safety thermostats can open and block heat. With power off, remove the rear panel and meter the cutouts and high-limit thermostats in the oven circuit. You should read continuity. Some models include a resettable style; if you find a red button on top, press once with the range cold, then re-test heating.

Controls, Locks, And Modes That Mimic “No Heat”

If the panel responds but the cavity stays cold, double-check settings. Confirm regular Bake (not Timed Bake with a future start). Cancel any delay. If your model includes a religious-holiday mode, it can mute feedback and restrict interactions; exit that mode through the control keys.

When you suspect a mode issue on a modern unit, the fastest path is the official help page for your exact model. Use your model number from the frame tag behind the drawer or door and look up the control steps in the online manual.

After A Self-Clean Cycle

Self-clean runs at extreme temperatures. Weak components can open during the cycle. If heat never returns afterward:

• Meter the rear safety thermostats and thermal cutouts for continuity.
• Inspect the bake element for a split or melted spot.
• Check the harness where it runs past hot panels for brittle or burned insulation.

Fix anything open in that chain before replacing the control. Many “dead after clean” cases are simple open cutouts or a failed element.

Temperature Sensor: What Readings Prove

The probe is a 1K-ohm class RTD used by the control to regulate heat. Near room temp, a healthy probe sits close to 1080–1100 Ω, then climbs smoothly as it warms. If the meter shows infinite resistance, the control sees an open sensor and refuses to heat. If the value is far off, the oven may stall or overshoot. Replace the probe if the reading is out of range or jumps while you move the lead.

Igniter: Why “Glows But No Flame” Still Means Replace It

A glow bar can light up yet fail to open the gas valve if it doesn’t pull enough current. That weak draw leaves the safety valve closed. If Bake sits there glowing with no flame after a minute, and your meter shows low current, swap the igniter. It’s the most common gas-side fix and restores heat in minutes.

When To Suspect The Control

Blown elements or weak igniters fail more often than boards. Move to the control only after you confirm these facts: full power is present, elements or igniter test good, probe reads correctly, and the safety chain is closed. If the board never sends power to Bake or misreads a good probe, a control swap is the logical next step.

Parts, Specs, And Simple Meter Targets

These numbers help you confirm a diagnosis and avoid guesswork. Meter readings vary slightly by model and room temperature, so allow small wiggle room.

Part	Normal Reading	Notes
Oven Temperature Probe (RTD)	~1080–1100 Ω near 70°F; rises smoothly with heat	Open or erratic = no heat or wild temps; replace if out of range
Flat Glow Igniter (gas)	~3.2–3.6 A when hot	Glows yet no flame usually means low current; replace igniter
Bake/Broil Element (electric)	Low ohms (often 10–40 Ω)	Any visible split or infinite ohms = failed element
Line Power (electric)	~240 VAC across L1–L2	120V present with no heat points to a tripped half-breaker
High-Limit/Safety Thermostats	Continuity when cool	Open after self-clean or overheat; some include a manual reset

Step-By-Step Repair Paths

Electric: No Heat At All

1. Reset the double-pole breaker; verify 240V at the outlet or terminal block.
2. Open the cavity; inspect bake and broil elements. Replace any split or open element.
3. Meter the probe at the connector; replace if out of range.
4. Command Bake; if no output voltage to the bake circuit with good parts, replace the control.

Electric: Heats On Broil Only

1. Meter the bake element first; replace if open.
2. If the element is good, check harness and the board’s bake relay.
3. Confirm the probe reads near 1.08–1.10 kΩ at room temp.

Gas: Glow Without Flame

1. Watch the igniter; time to flame should be under a minute.
2. Measure igniter current; if below spec, replace the igniter.
3. If current is good but no flame, check safety thermostats and the valve.

Gas: No Glow, No Click

1. Confirm power to the control and that Bake is commanded.
2. Check door switch and safety thermostats for continuity.
3. Meter voltage to the igniter circuit; trace back to the board if dead.

Small Tweaks That Restore Normal Cooking

Calibrate When Temps Are Off, Not When There’s No Heat

Use calibration only when the oven heats but runs a little high or low. If the cavity stays cold, calibration won’t help; you need the checks above.

Replace Gasket If Heat Leaks

A torn door gasket lets heat escape and stretches preheat times. If you see a gap, swap the gasket to speed recovery and keep temperatures steady.

When A Technician Makes Sense

Call in a pro when you have recurring breaker trips, a gas smell, burnt wiring, or no tools to meter live circuits. Also reach out if the unit shows error codes that reference the sensor circuit or the board. A trained tech can run the factory test steps, log readings, and confirm the exact failed part.

Model-Specific Notes

Frigidaire builds many variants under one series. Your model tag is on the frame behind the drawer or door. With that number, you can look up the official manual and control steps, including special modes and lock states. Use those instructions for the fastest route out of a dead-heat situation.

Helpful Links For Modes And Specs

If your panel seems responsive but heat doesn’t start, check the brand’s page for religious-holiday mode and exit steps. You can also review the basic “no heat” article for quick setup checks and burner tips. Keep these handy while you work through the lists above.

Bottom Line

Most no-heat cases trace to four items: half power, a failed element, a weak glow bar, or an out-of-range probe. Work from simple to advanced, meter what you can, and replace only the part that fails a test. That approach saves time, saves parts money, and gets dinner back on schedule.
