My Baumatic oven now displays F4E0 after a power surge, the fan still works but there is no heat.

Check the elements for continuity. Some ovens will do strange things if one element fails due to shared returns.

here is a search to the element you need on ebay etc or epares
shop around for the best price inc post etc.,..

If the oven is electrically heated, then more than likely, the oven element has failed.

This is located behind a removeable cover at the rear of the oven.

if it is the b180, the answer (having just fixed this) is really simple.

The coily bit is the oven element - it will have gone. A new one from eBay cost me about 6 quid.
[WHEN IT ARRIVES !]

Turn the power off.
Inside the oven use a philips screwdriver to remove the 4 screws (KEEP THEM !)
You will see a coily thing and a fan.


You unscrew 3 more screws (2 on the left and 1 on the right).
(KEEP THESE TOO!)

now ... bit tricky, have the new one inside the oven and take each wire off one at a time and put it on the new element.

Screw it back on but DONT put the last panel back in.

Turn the oven on maximum for about 2 minutes and see it glow red.

Turn the oven off. Make a cup of tea and have a couple of biscuits while admiring how good you are and waiting for the element to cool down!!!

Put the final panel back in place. Whole thing (including a cup of tea) takes about half an hour.

You will probably find that it is the oven element that has failed.
This is to be found at the rear of the oven compartment behind a removeable cover.
Hope this helps.

whilst the fan is running the heating element which is usually in parallel with it should heat.. This usually means a faulty element..

check elements thumbs up

If fan is working then the element has probably gone

I have the same model steel finish was looking for parts mysel and came across yr dilema... I had that problem before . I always turn left knob to fan.. turn heat to whatever say 200 then click the button with the hand signal and i never touch any other button it alays does the job for me.. i cant cook so never need to touch ant other button ,,,, its a timer issue that stops it heating up swtch it all off at spur or mains start it up again

I think your thermostat is broken, try replacing it with a new one.
