Re: neff oven ui420ovgb/o1
MTR213 from Qualtex @ £31.37 + VAT will fit. Looks different at first but when the old one is removed, the holes on the motor mounting panel line up perfectly with the triangular mounting plate. Just move the motor around until they line up. 😉 The 3 screws holding the original motor will be too long so just swap them with the shorter back cover screws (making sure the longer screws are fitted in the corners of the back cover).
Hope that helps,
Steve.
