# Electrolux dryer not heating repair

### The motor and the element run on different voltages

That single fact explains the commonest pattern on this job. The motor takes 120 volts and the heating element needs both legs of 240, so a dryer that tumbles happily and never warms is frequently a supply problem rather than an appliance one. This maker publishes two codes saying exactly that — H2/B2 and H4/B4 — and both point outside the machine. If that is what we find, we say so rather than fitting an element.

What this involves

Tumbling without heat points at the supply as often as at the element

H2/B2 and H4/B4 are this maker's codes and both point outside the machine

If it is the circuit we will say so rather than fitting a part

Check whether anything else on 240 volts has changed

A lost leg takes the range or the water heater with it. That coincidence is the single most useful thing you can tell us on the phone.

Reset the breaker once, fully

Off and back on, once. Repeated resetting of a breaker that is doing its job is not diagnosis.

Then test the element, thermostats and thermal fuse

In that order. A blown thermal fuse is a symptom of restricted airflow, and replacing it without clearing the duct simply blows the next one.

### What should I check before calling?

Whether anything else on 240 volts has gone strange at the same time — the range, the water heater, the air handler. A lost leg takes them together, and that coincidence is the most useful thing you can tell us.

### The thermal fuse blew and I replaced it.

Then find out why. A thermal fuse opens because the air was restricted, and replacing it without clearing the duct simply blows the next one.
