- “Tumbling without heat points at the supply as often as at the element”
- “H2/B2 and H4/B4 both point outside the machine”
- “Check whether the range went strange at the same time”
Symptom
Electrolux dryer not heating
On an electric dryer this pattern says something specific before anybody opens the machine. The motor runs on 120 volts and the heating element needs both legs of 240, so a dryer that tumbles happily without heating is very often a supply problem rather than an appliance one. This maker publishes two codes that say exactly that — H2/B2 for the supply, H4/B4 for wiring — and both send you outside the appliance.

Three ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
A leg of the supply is missing
A lost 240-volt leg leaves the motor running on 120 and the element dead. It usually takes another appliance with it, and that coincidence is the diagnosis.
Dryer not heating repair from $149 -
The thermal fuse has opened
It opens because the air was restricted. Replacing it without clearing the duct blows the next one.
Dryer vent cleaning from $119 -
The element or a thermostat has failed
The straightforward repair at the end of the list, and it is worth doing the wear parts around it at the same time.

Look for other 240-volt oddities
The single most useful thing you can tell us on the phone about this symptom.

02
Reset the breaker once
Once. Repeatedly resetting a breaker that is doing its job is not diagnosis.
-
03
Hold the lint filter up to a light
Softener residue passes lint and blocks air while looking perfectly clean.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Electrolux dryer not heating
What to do in the next ten minutes
Check whether anything else on 240 volts has misbehaved at the same time — the range, the water heater, the air handler. Reset the dryer breaker once, fully off and back on, and no more than once. Clean the lint filter and look through it against a light.
Why the supply comes first
It is counter-intuitive: the appliance is the thing that stopped working, so the appliance must be broken. But the specific pattern of a dryer that tumbles and does not heat maps precisely onto losing one leg of a 240-volt supply, and that fails outside the machine — at the breaker, at the outlet, at the cord, or at the utility. This maker publishes two codes pointing there. If that is what we find, we will tell you rather than fitting an element.

Questions about Electrolux dryer not heating
It heats a little but not much.
That is more likely the appliance — a partially failed element or a thermostat cycling early — because a missing leg gives no heat at all rather than weak heat.
Is it worth checking the vent first?
Always, and it costs nothing. A restricted vent is what opens thermal fuses, so it is the cause behind a good share of no-heat calls even when the fuse is the part replaced.
