Sooo, one of my ovens didn't seem to be holding temp.  And true to what we always advise on here, I hung my oven thermometer in the oven, turned the oven on, and nope, the oven would not go past 300 degrees.  Well, that's a problem so I called the repair guys.  They've worked on this oven before and I pretty much hoped it would be the probe (thermostat) rather than the electronic board (like a motherboard in a computer) because that thing was nearly $600 last time I replaced it. 


A replacement oven is about $1200 because of the size and specs I wanted.  So repairs are cheaper than new, mainly because the electronic boards fail with some regularity on ALL ovens with touch screen controls where the heat escape vent is too close to the screen.  (Nearly all oven designs.)


The repair guy came over, tested the probe (thermostat) and it was fine.  All indications are that it's the electronic board.  ::sigh::


Before the repair guys (2 for the second trip) came over they asked me to turn the oven on at 450 to see if the bottom of the oven heated.  It did.  All indications are again that it's the electronic panel.  ::sigh::


The guys show up.  The oven is hot.  They place their temp probe into the oven that has an external readout.  The oven is indeed hot.  It's 450 and holding.


The problem all along?



Wait for it.


The cheap oven thermometer that I hung from the rack to check the temp.  You know, the kind you throw in your cart at the big box store?  For about $1.49.

These guys saved me nearly $600 by triple checking the oven to verify that there was nothing wrong with it.  I love these guys.

So...did they suggest a better way to test the temp to be sure that it's heating like it's supposed to?  We rely on those silly little oven thermometers!  Sure glad it didn't cost you  a new electronic board.  I've never understood why they didn't build these ovens better if that is so tempermental with heat.  They put them right at the top of the oven where the heat automatically rises when you open the door....but no protection for the electronic board at all!  I have a Thermador double oven and the electronic board is right above my upper oven and has been replaced a couple times.  Lucky for me, though, I decided to invest in the extended warranty when purchased and have renewed it 3 times.  Am glad I did so, because they've been out several times for expensive repairs and I didn't have to spend a penny!

The repair guys just said to buy a new thermometer.  :)

Actually they left me theirs.  Seems the ones we buy are really only good for 3 months max.

Oh and good for you on the extended warranty.  Good decision.  The repair guys said all brands are built the same so that the heat damages the electronic board.  It's simply a way to sell more ovens.

Guess that's why they're so cheap!  The ons I have I paid a little more for, but can't remember the price.  It was highly recommended somewhere, but can't remember that either!  It's made by Cooper.  So far, so good.  Will see in 3 months,I guess.

I'm glad those guys checked and saved you all that money. I'm breaking in a new oven and I had to get two oven thermometers just to be sure. Note to self: Change out the oven thermometers every 3 months.

That's why I have always recommened the use of a mercury one.  *MUCH* more accurate.  Taylor is one brand.  Yeah, they are a bit on the expensive side, but in the long run they are accurate and long lasting.
