Storage Heater Thermal Fuse Query

[papafett]

Hi all,

I'm trying to sort out a storage heater in our house that has stopped working - its still getting power (the wall switch for it has a light) and all other heaters in the house are fine. It went from working one night to nothing the following (not a steady decline).

Research suggested it was the thermal fuse/link so I purchased one listed as the right one for my model (TSR18MW-79354S) but couldn't see anything like it when I took the cover off. Here's what I bought:

Anyone have any ideas?

I've found what a replacement for the whole thermostat module here:

But its £35 and I don't want to but it if I don't need it!

Thanks in advance for any help.[/url]

you need the meter or continuity test to find out what has failed

Thanks for the response Andy, yep putting the meter on it is the next task, I was just hoping before I take the cover off again if someone can confirm if they've seen this setup before and if the thermal fuse I've bought wont fit (as I suspect).

I may be wrong, but I think this model has a resettable thermal cutout, where the cream piece of plastic is. Does anything there push and click to reset? If that has gone you need to work out why, it could be the input thermostat has stuck on. One way to check this is to use a hair drier on the bulb part of the thermostat, usually located at the bottom of the heater, and put a meter on continuity across the input thermostat and see if it switches on and off.

Is it the bit sticking up above the left side of the brown square part?

Are you referring to the bit I've circled?

If so, yes I think it was sticking up and I pressed it down out of curiosity and thought it made a clicking noise. I'll opened it up and take a closer look.

So I'm guessing the thermal fuse I have (pictured) isn't for this model then?

Thanks again

No, it isn't.
