Oven with power but no heat
A blown thermal fuse — a cheap, fast fix that gets mistaken for "the whole unit is dying" more often than almost any other oven fault.
The Call
What We Hear
The oven turns on, the display works, but it never actually heats up — no matter how long you wait.
A common way this fault gets described to us
Whirlpool double oven — heat path
The thermal fuse is a one-time safety part in series with the heating circuit — once it blows, nothing downstream gets power.

Symptoms taken
Power and display working, no heat from either cavity — the classic thermal-fuse pattern.
On site
Fuse confirmed open
Continuity test found the thermal fuse open, everything else in the heat circuit intact.

The Diagnosis
What Was Actually Wrong
Root Cause
Blown thermal fuse cutting power to the heating circuit
A thermal fuse is a one-time safety part: it trips once, usually after the oven runs hotter than its design limit for some reason, and then permanently cuts power to the heating circuit until it’s replaced. It doesn’t reset itself.
Everything downstream of the fuse — both elements, the control board, the door switch — tested fine once power was restored, which confirms this was a single-part failure rather than the start of a bigger control problem.
Repair Path
How We Fixed It

Step 02
Thermal fuse replaced
OEM-spec fuse fitted from van stock.
OEM PART · VAN STOCKStep 03
Full heat cycle on both ovens
Both cavities run to temperature and held before sign-off.

If This Is Happening To You
Thermal fuse?
Power on, display works, but no heat?
That specific pattern is the thermal fuse more often than any other single cause.
Doesn’t reset on its own
A tripped thermal fuse stays open until it’s physically replaced — cycling the breaker won’t fix it.
Note if it happened after self-clean
Self-clean cycles run hot enough to trip a marginal fuse — worth mentioning on the call.
Usually a same-visit fix
It’s a common enough part that it’s normally carried on the van — ask when you book.
A thermal fuse is a cheap, fast fix — the kind of oven repair that gets mistaken for "the whole unit is dying" when it is a single small part.
