hob question

[markysparky]

hi

I fitted a new hob for a client, He contacted me and said that when he turns on the back two rings, it shows the warning lights that shows it is hot, these are the wrong way around. So the left light goes on when the right ring is heating up and vice versa? Any ideas why. An engineer is coming out to check the product.

I guess it is internally the wiring to the indicator lights have been switched in production?

The sales guy said if i had wired it up wrong he would charge me!!! cheeky s>d.

It all works fine apart fom the two warning lights mixed up. Any ideas?

Almost impossible to wire them up wrong, so would be an internal problem beyond your control.

Some 3phase type ovens/hobs have solid link bars for connections to single phase so I doubt even this could show the same problem you describe.

Have an invoice ready for the engineer when he comes to charge

Has to be an internal connection problem Marky . Nil Illegitimus Carborundum !

Assuming you wired it to the supply only and did this correctly, I would guess your fine. It sounds like a fault in manufacture or assembly, but not on your part. Sit back and wait for the buggers to ring and apologise for questioning your professional integrity and competence. :Y But don't hold your breath whilst doing so!

Its common practice for engineers to charge if it is installed incorrectly and fair enough.

Just make sure you are there when he is.

I would imagine appliances are the same as other electrical stuff not tested.

I fitted an cooker this week and the hob will not work because the switch that stops it coming on if the lid is down was faulty and this was purchased through m&s.

As you suspect Batty, appliances generally are not 100% tested at eol. If I were to hazard a guess I'd say they probably perform 10% testing. It's all in the name of cost cutting.

About a dozen years ago I considered going into product engineering in white goods. I quickly changed my mind. I went for two interviews and I was verging on telling the interviewers (who were engineering managers) how to conduct the interviews. They hadn't a clue. The money just wasn't there - they were talking about 60% of what I was earning in the automotive sector. And you know what they say about paying peanuts.....

It just doesn't surprise me that white goods are so poor for quality. It's all about cost.

OP, just be there when they are there and have your bill for your time ready to hand over. One way to improve the quality of white goods would be to ensure the cost of warranty exceeds the cost of testing. So make your contribution.

I had to make a repair on a "brand new" rangemaster cooker that I installed. There was a dead short from L to E

It turned out the customer bought it 6 months ago as "new, ex display" from ebay. Because he had it 6 months, the ebay seller did not want to know (90 day guarantee) and when I phoned Rangemanster, it turned out that even though it had never been used it was > 5 years old (from the serial No) so they didn't want to know.

At this point the customer was almost in tears, so I agreed to open it up to see, and found a wire pinched between one of the controls and chassis, a clear manufacturing fault and clearly not tested, but thankfully an easy repair.

Yep, I've found trapped wires in Rangemaster stuff. Brand new too. Great gear let down by poor manufacturing. (we have a Rangemaster dealer in the town, so I see quite a bit of this stuff).

Did I tell you guys about my friends mom who's oven in their cooker stopped working and they wanted me to have a look at it.

Well they have had the cooker for 7 years, I presumed they knew how it worked, I took it to pieces testing element, switch, thermostat, etc couldnt find any problems at all although i am not an engineer or got much experience in these items.

Anyway resigned myself to putting it all back together and it turns out the dad made a right cxck up when he messed with the digital clock as when i pressed a button under the lcd display it now works.

He was with me all of the time that i was trying to fix it, his Mrs was in the lounge and when it came on and we realised his big mistake (OK mine as well for not originally checking the user manual) he wanted me to pretend to his wife that i had found a dodgy connection.

I couldnt lie to her and she knew something was up especially as I just could not stop laughing:^O:^O:^O

A very common problem, the oven timer often gets set to auto when being cleaned and has to be reset to hand before it will work.

been to a few of those jobs... dont even need to take any tools
