An electric oven that will not heat is more often a failed bake element than a blown fuse. Look at the element first - a broken one usually shows a visible split or blister. Only when the element and the breaker check out is the fuse worth pulling the back panel for.

This guide covers how to tell those two apart, where the fuse sits, how to test it, and why a blown one usually means something else failed first.
Check the element before the fuse
On a standard electric range the bake element is the loop across the bottom of the cavity. Let the oven cool completely, then look along its whole length. A failed element frequently shows a split, a blister or a bright scorch mark at the failure point. Many fail visibly, and that ends the diagnosis in thirty seconds.
An important clue: if the broil element at the top still glows but the bake element does not, you have a failed bake element, not a fuse. A blown fuse takes out the whole heating circuit, not one element.
Check the breaker properly
An electric range runs on a 240-volt double-pole breaker. These can fail on one leg, which produces a distinctive symptom: the clock, lights and control panel all work on 120 volts, but nothing heats. People read that as "the oven has power, so it must be the oven," and it is actually the breaker.
Switch the breaker fully off and back on. If the panel lights up but nothing ever heats, have the voltage at the range checked before you buy parts.
Where the fuse is
Not all ovens have a user-serviceable fuse. Many modern ranges protect the heating circuit with a thermal cut-out rather than a cartridge fuse, and some use a fuse soldered to the control board.
Where a replaceable fuse exists it is behind the rear access panel, near the terminal block where the supply cable lands. On wall ovens it may be behind the trim or accessible only once the unit is drawn out of its cabinet.
Testing and replacing
Step 1: Kill the power at the panel
Unplugging is not enough on a hardwired range or wall oven. Switch the breaker off and confirm it is dead before touching the terminal block. A 240-volt circuit is not one to take chances with.
Step 2: Open the rear panel
Remove the screws around the back panel and set them aside. Photograph the wiring before you disconnect anything.
Step 3: Test for continuity
A multimeter on continuity across the fuse should read near zero resistance. Open circuit means it has blown. Test any thermal cut-out in the same circuit while you are in there.
Step 4: Replace like for like
Match the amperage and type exactly to the part number for your model. A higher-rated fuse will carry a fault current the circuit was never meant to carry, which is how an electrical fault becomes a fire.
Why it blew matters more than the fuse
A fuse or thermal cut-out opens because something drew too much current or ran too hot. The usual suspects are an element that has shorted to the chassis, a failed relay on the control board welded closed, or a cooling fan that stopped and let the electronics overheat. Replace the fuse and leave that in place and the new one goes the same way.
Frequently Asked Questions
My oven heats but the temperature is wrong. Is that the fuse?
No. A fuse is all-or-nothing. An oven that heats to the wrong temperature has a drifted or failed temperature sensor, and on many ranges that is a calibration adjustment rather than a part.
How much does this cost to fix?
A bake element is typically $40 to $100 for the part. Our diagnostic is $100 and applies to your repair labour, with labour on a typical oven repair in the $225-$300 band.
Can I run the oven on the broil element until it is fixed?
You can, but it will not bake properly - broil heats from the top only, so anything in the oven browns on top and stays raw underneath. It also tells you the bake element or its circuit is the fault.
When to call
If the element looks intact, the breaker is good and the fuse tests open, book an oven repair. Finding the overcurrent that blew it is the part worth paying for. Our technicians hold the Technical Safety BC licence for gas work as well, if yours is a gas range.
