Westinhouse oven and simmerstats

rak1, Mar 28, 3:03pm
We have a 12 yr old model PSL632s that we have had since new and I have replaced every simmerstat twice in that time and the oven fan once. Does anyone have any idea what could be causing such a failure rate? The replacement units have come from authorised dealers and certainly look identical to the originals. Thanks for any suggestions.

12 year old stove and only replaced them twice, then you are doing quite well. Those blue simmerstats are always playing up and unreliable. Made in China as stated. Does not seem to be any standard quality control. Some of them I have seen are 10 years old and only just failing. Then the next one I see is only 1 - 2 years old and failed already. They are the original brand and all manufacturers that use them i.e. F&P, Simpson, Westinghouse, Atlas etc have the same issues. Some people on here have previously stated that turning them on/off in only one direction will magically make them last, but it doesn't make any difference what so ever.

Everything is Made in China almost. It's not madie IN China that is the issue, it's made BY china.

That is, the components used in things.
Motherboards for instance, certain of them use chinese capacitors and fail often, others use Japanese capacitors and don't.

Frustrating eh. Guess I will just have to start buying them in bulk.

If they are Smiths stats they are chinese made crap . unfortunaly cant get anything else . Me i have a Blanco fan wall oven & bench top elements made by Steelfort in NZ many years ago & works perfectly & nothing has ever gone wrong in the 25 years ive had it bought second hand . Last house had a Moffat again excelent quality

We had problems in our rentals for years until a sparkie gave us the solution. You have to turn the elements of from high through low to off. If you turn them off from high straight to off then you will stuff the simmerstat. Now we have trained our tenants, no more problems

Why would it make any difference? Is it something to do with a sudden drop (current, voltage, temperature) by going from high to off? In nearly 50 years of owning and operating ovens I've never had to replace a simerstat. Going out to buy 5 tomorrow as I know what's going to happen now!

I bought replacement simmerstats from a vendor on Trademe that had two price points. The cheaper ones had a lesser warranty, which, foolishly I bought. They crapped out about a month after the warranty expired.

In a world where all sorts of electronic wizardry is available quite cheaply, one would think a decent quality simmerstat could be bought for a reasonable price.

It doesn't make any difference at all. If it did, the simmerstat manufacturer would make them so that they could only be turned off one way or the stove manufacturer i.e. F&P, Westinghouse would tell the customer in the user manual to only turn off one way or mark the panel with an arrow etc.

A common way of “killing” simmerstats us to turn them the wrong way. that is attempting to / forceing them past High to get to Off. the el-cheapo one have little in the way of a mechanical barrier to stop this !

Dammit, I have only had one fail. I shall have to take it apart to see what's wrong with the design. I usually fix 100 year old electrical devices.
