[Closed] Swapping a like for like oven.

I've got similar issue, though doesn't have to be like-for-like other than something that fits the same hole and does the job. Original was an MFI job (Howdens may do them I guess). Has two power sources though. One is wired in and the other is just a plug and powers the display.

I've pulled the thing out a little by hand to fix knackered buttons on the display so looks like the whole thing just slides out and other than that it must just be wired in, so same question on the wiring / will I die etc. Actually wired in, does that legally require a pro to inspect it?

If it's not exactly the same model, would the housing need adjustment or are they all same shape and can just drop in a replacement (of the same size)?

Watch out for the ampage, some newer oven require a higher ampage, and this then needs a higher amp fuse on the consumer unit.
Most suppliers charge a nominal fee for fitting or an electrician could do the dangerous bit for a small cost.

The fitting is a £100 which if it’s the same as changing a plug is a lot.
Have followed the cables and they end up in the fuse box. I’m not touching that!
If we are spending £600 on an oven I really want to know that I’m not responsible if it doesn’t work.

Mine goes to a fused spur(right word?) which is easy access.

Slip in, slide under or stand alone oven?
Depends upon the current draw. Simple single ovens can run off a spur from a ring main but this is poor practice. Double oven or if you want to do it properly - 4mm or 6mm 2&E back to a 30 or 40 amp breaker on the consumer unit. Cables should have terminal plate in the wall and a loop of heat resistant cable to the oven.

Pull the oven right out - should just slide out assuming slip in or under worktop but again should be secured with a couple of screws at the sides

See what is behind it. And yes - there should be a double pole isolator switch ( or swi9tched fused s[pur point that sould be accessible with the oven in place but often is not

the actual wiring is a simple as wiring a plug usually

Pull the oven out, check what you have, check the ampage on the old and new oven.

Make sure you switch off the power to the oven from the fuse box. Our 'new' build 20 years ago, the builders labelled the oven and shower the wrong way. I wondered why the shower was still 'working' when I powered it off - the oven was off instead. This was as I was replacing the shower. Always double check.

Yup, I've had our built-in ovens in an out numerous times over the years - replacing grill elements etc. Ours is on a 30A circuit - isolate at the main switchboard - check that the terminals are not live and simply change-over the 6mm 3-core cable. There's usually a couple of retainer screws into the wall unit behind the trim. There are a few 'standard' sizes of oven apertures - just find a similar size replacement.

also don't assume the wiring is the correct diameter for the oven in there at the moment! Check and double check!

If it's 6mm twin and earth i would just swap, unlikely to need bigger than this.
I would check first though.

The majority of single ovens are 13a these days and just plug in. If a higher power one then isolating the supply and swapping like for like is an easy job too. The only difficulty would come if you had a 6mm supply for 30a and then you bought a 13a oven as it would need to be fused down to the correct rating.

As above about checking the ampage of the new oven. As long as the cable and RCD are suitably rated it’s an easy job however strictly speaking its a job which under the building regs needs signing off by a registered electrician (All bathroom and most kitchen wiring jobs do)

If it is the identical oven then just make sure you switch off the power (then check again) and rewire it up - there are only three wires so it won't be difficult. But, to avoid any doubt, take a picture of the wiring set up on the original oven before undoing anything.

I wouldn't hesitate for a second to do it and I am by no means a DIY expert.

If it was gas I wouldn't go near it.

Piece of **** IMO, I switch the entire mains off to do any electrical work tho!

Might your oven be capable of repair?

I've just fitted a new oven this afternoon, swapped out a built under single for a bigger double. Despite my best efforts at measuring I had to remove the kick board from the bottom and drop the carcass to get it in. I'm just about to measure the kick board got a cutout so I can put it back. What should have been a 20 minute job has turned into the entire afternoon.

I hope you made sure the wiring was up to scratch? single ovens generally under 13 amp, doubles over 20

this is the key thing with wiring IMO.

Yup, wiring was checked by someone wiv electrickery qualifications before I installed it.
