Storage Heater Technical Information

Feb 19, 2007 5 Replies

Hi, I have a UNIDARE WMS724N that has failed. I need a circuit schematic so that I can search out the source of the failure. I know that it has three heating elements & two thermostats. I think it unlikely that all three elements have failed so failure of one of the thermostats is high on the list. I understand that one of the thermostats protects against runaway max temperature. If anyone out there can help please email.

Have you checked any fuses it may have?

The stats will be in series with the elements in parallel

I had to fix a heater with all 4 failed. Check them with a meter or continuity tester.

This has some exploded diagram's and parts lists:

Incidentally - many heaters use a generic Dimplex 850 Watt element. I got some replacements at a good price off e-bay.

The thermostat may have a overheat device that might need pushing to reset it.
