Oven Not Heating? Here's Why (And How We Fix It in Edmonton)
An oven that won't heat brings meal prep to a complete stop. Here are the five most common causes our Edmonton technicians find — in both electric and gas ovens — and what each repair costs.
Why Your Oven Isn't Heating
An oven that won't heat is more than an inconvenience — it brings meal prep to a complete stop. Whether you have an electric range or a gas oven, most no-heat faults come down to a small set of components, and our Edmonton technicians resolve the majority of them on the first visit.
Electric and gas ovens fail differently. Electric ovens rely on bake and broil elements, a thermal fuse, and a temperature sensor. Gas ovens use an igniter, a gas valve, and a safety thermostat. Knowing which type you have helps narrow the diagnosis before a technician even opens the appliance.
1. Failed Bake or Broil Element (Electric Ovens)
The bake element sits at the bottom of the oven cavity; the broil element is at the top. Either can burn out over time — you may see a visible crack, blister, or dark spot on the coil, or the element may simply stop glowing red during a preheat cycle. When the bake element fails, the oven won't reach temperature; when the broil element fails, the top of your food stays raw.
Element replacement is one of the most straightforward oven repairs we perform in Edmonton. Parts and labour typically run $120–$220 depending on the brand. Whirlpool, Samsung, LG, GE, and Frigidaire elements are widely stocked and most replacements are completed in under an hour.
2. Faulty Igniter (Gas Ovens)
The igniter is the most common cause of a gas oven that won't heat. It serves two functions: it glows to ignite the gas, and its electrical resistance signals the gas valve to open. When the igniter weakens with age, it glows but never gets hot enough to trigger the valve — so gas never flows and the oven stays cold.
A weak igniter often takes more than 90 seconds to light the burner, or fails to light it at all. Igniter replacement costs $150–$250 in Edmonton. Because this repair involves the gas supply line and burner assembly, it must be performed by a licensed gas appliance technician. All Maple Leaf technicians hold the required Alberta gas certifications.
3. Blown Thermal Fuse
Like dryers, ovens contain a thermal fuse — a one-time safety device that blows permanently when the oven overheats. A blown thermal fuse leaves the oven completely dead or unable to heat past a low temperature. It's most common on self-cleaning ovens, where the extreme heat of a cleaning cycle can trip the fuse if ventilation is restricted.
Replacing the thermal fuse costs $80–$160, but the root cause — a blocked vent, a failed cooling fan, or a faulty thermostat — must be identified and corrected at the same time. Installing a new fuse without fixing the underlying issue will cause it to blow again within weeks.
4. Defective Oven Temperature Sensor
The temperature sensor is a small probe mounted inside the oven cavity that tells the control board the actual temperature. When it fails or drifts out of calibration, the oven may under-heat (food stays raw), over-heat (food burns), or cycle erratically. You might notice the preheat indicator light going out far too early, or the oven never reaching the set temperature at all.
A technician can test the sensor's resistance with a multimeter — at room temperature it should read approximately 1,080–1,100 ohms on most models. A sensor replacement costs $100–$200 including labour and is one of the more cost-effective oven repairs, often restoring precise temperature control to an otherwise well-functioning appliance.
5. Control Board Failure
The electronic control board manages every function of a modern oven — preheat cycles, temperature regulation, self-clean, and timed bake. When the board fails, it may stop sending voltage to the bake element or igniter entirely, or it may display error codes: F1 or F3 on Whirlpool and Maytag ovens, SE or E-0E on Samsung, F10 on Frigidaire.
Control board replacement is the most expensive oven repair, typically $250–$450 depending on the brand and model. Before authorising a board replacement, it's worth comparing the cost against the age and value of the appliance. Our technicians will give you an honest assessment — if replacement makes more financial sense than repair, we'll tell you.
When to Call a Technician
Before calling, check the basics: confirm the circuit breaker hasn't tripped (electric ovens draw significant current and can trip a double-pole breaker), and inspect the bake element visually for cracks or burn marks. If the element looks intact and the breaker is fine, the fault is internal and requires a technician to diagnose safely.
