Hotpoint TDC30 Tumble Dryer Not Heating

I was asked by a friend to look at there tumble dryer for them, the fault being that it was not heating at all. So for my sins I said I would have a look.

I looked at the heating element 1st of all and could see some degradation of the element, but the heater did meter out ok @ 80 ohms I believe from memory.

The two thermostats were short circuit as expected, so no need to change those.

I decided to change the heating element as I thought it may be causing the problem. Whilst the element was on order my friend decided to try the tumble dryer and it worked for a couple of days ok. It then failed to heat again.

I changed the heating element and the tumble dryer still refuses to heat at all. I have metered out the new element and once again checked the thermostats all are ok.

I am now at a bit of a loss as to what the problem may be. Any help/suggestions would be greatly appreciated. Oh btw the drying light does not come on at all.

Thanks in advance for any help/suggestions.
