I am not a qualified electrician.
Our Beko D532 (S - which I think just refers to the colour - silver?) electric cooker developed a fault last week after 4 years from new. The oven and front and back hotplates stopped working. The grill and two left hot plates continued working. Building on the advice of this site ... I did the following - which worked!
1) Switch off the cooker supply at the fuse box and at the wall connection! To be safe!
2) Unscrewed the back of the cooker (there are quite a few fixing screws) - and take care .... the back plate of cooker is sharp .... so wear gloves.
3) I could identify two thermal fuses - one was connected with a white wire at the bottom right, the other was connected with a red wire 2/3 of the way up on the right. Both were surrounded by transparent shrink wrap. The thermal fuse was connected each side by a rigid wire and climped to the red and white wire. The reference on each fuse was M/CR OTEMP, STLC HV, E5AOO, 9U_TF144C - I don't know what all this means but advice from the supplier .... the TF is thermal fuse and the numbers after are the temp rating of the fuse 144 Centigrade. At this stage I didnt know, with certainty, which fuse worked the faulty areas? (but later established the white wire connected fuse protected the oven and right hot plates).
4) I called Sinolec components www.sinolec.co.uk who were very helpful and ordered 4 thermal fuses (so I had spares) They cost £0.51p plus vat each and I also ordered pillar terminal block (£0.75p plus vat) to connect the new fuses. Their thermal fuses cover different temperatures - I bought the 152 C one - on advice - as this was within the range of 144 C currently fitted.
5) With again power switched off - I cut the existing fuses out (and shrink wrap) and connected one of the new thermal fuses and reused the one that was still functioning ok using the connector block. I then thoroughly wrapped each fuse with insulation tape. (I did try the oven before I replaced the back (taking care to keep very clear of any wires) and the oven and faulty hotplates didn't switch on .... but .....when I reconnected the back of the cooker and switched on they all worked fine!? Not sure why?
We have now cooked a few meals on the mended cooker and its fine .... I was grateful for the help on this site and wanted to add to the advice .... I did try throwing the fuse on the ground to fix it ... as advised on this site ... but didn't work for me?!
