Hoover TV630 – Filter Care Light on TOC not o/c

[admin]

I have a Hoover TV630 tumble dryer and the filter care light is permanently on and heat is not being produced.
Looked though the rest of the site and the thermal fuse on the heater unit is normally the culprit but i’ve checked the fuse with a multimeter and it is not open circuit. Anything else it could be?

Jon,
The reading through the safety fuse should be near as spit 0 ohms. If you are reading 30-40 ohms, you are getting a back reading through the heater circuit and the fuse will have failed.

Please clarify and more help will doubtless follow.

I’ve disconnected the fuse from the dryer and it reads 0 ohms

Any o/c component attached to the element or the element itself will give the same symptom Jonathan.

Check the two thermostats attached and the element for continuity, the stats should both be c/c.

Sorry Dave thats gone straight over my head.

Just to clarify what i’ve done, i’ve taken the panel off the back of the dryer, removed the thermal fuse from the heater unit (silver thing with 2 tags) put a meter across the 2 tags on the fuse and the reading is 0 ohms. To me this means the fuse is ok.

Basically, if either the heating element or the thermostats are faulty the filter light will come on, it’s not always the thermal fuse that causes it.

Now I get you.

If I buy the replacement heater unit thats listed in the shop will it solve the problem?

Hopefully yes, although I won’t guarantee it, it’s 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} to do the trick for you.

Thanks for your help. I’ve ordered the replacement heater. Hopefully that will solve the problem.

Fingers crossed eh 😉

Let us know how you get on please.

I have the same problem with our TV630. I did what was suggested and checked the thermal fuse , it is ok. The heating elements also seem to be OK but there is alos what looks like a zenner diode which is o/c connected to the ehating elements, could that be the problem?

Thanks

That’s a Thermocouple Alan, let me know the temperature rating (i.e should read something like 130C on it) and I can fix you up with a replacement 😉

Just email me :tup:

What you are describing Alan sounds is the thermal fuse by the sounds of it, there’s certainly no electronic components there anyway 😉

My TV630 had exactly the same fault. I ordered a spare heater from the online shop after reading comments on this forum.
This has done the trick and the dryer is working perfectly. Many thanks for an excellent service.

The original had a blown (o/c) thermal fuse. The replacement heater is slightly different in construction – there is a black cylindrical component with 2 tags marked with a temperature (I assume a thermostat) but it does not have the same thin metallic tubular thermal fuse as the original but instead there is a metallic cylindrical component about the same size as the black one, also with 2 tags. What exactly is this?

The replacement is also heavier and more robust than the original, so maybe it will last a bit longer.

The right hand device is the thermostat, the left hand one is a single shot thermal safety device – it replaces the microtemp device of the earlier heater.
