New Appliances Have Electronic Controls
If you have any new appliance, it
probably has an electronic control panel that keeps it functioning. The control
panel is the brain to the appliance, so we found out with our Whirlpool electric
range. With no brains, the appliance has no sense.
We returned from a two-mile walk and
decided we'd cook a frozen pizza for supper. I turned on the oven and pushed the
temperature panel to stop at 400 degrees. When the preheat had less than a
minute to go, I popped the pizza in the oven and went to watch television for 15
minutes while the pizza cooked. I heard the buzzer when the preheat
completed.
Don't Use Your Appliances When You're Out
I was just in the next room, but
smelled something strange. Got up to check on the pizza and saw that the oven no
longer showed 400 degrees, but had something that looked like F-3 on the panel.
The pizza smelled like it was burning and there was an electrical smell in the
air.
I pulled on the oven door. It
wouldn't open. I peeped through the glass and could see the coils were hot and
continuing to heat. I called Hubby. He ran to the garage to turn the breaker off
while the house was filling with smoke and burned-pizza odor. We opened the
doors, trying to prevent the smoke alarm from attracting the
neighbors.
The door wouldn't open even after the
breaker was turned off. The pizza continued to burn because the oven was at a
high temperature.
I went to the Internet to check to
see if this happened to other people. It appears that it is fairly common, but I
couldn't get the oven door open to locate the serial number or style of the
oven. Even the 800 number is inside the oven.
I rifled through the warranty files
to locate the owner's manual and installation booklet. There is no information
about this problem in the literature.
How the Electronic Controls Work
After an hour or so, the oven
door could be opened and we took the black pizza out and threw it away. The next day, I
called Whirlpool and reported the dangers of what happened. They said that was
normal and "the way the oven was intended to work." I suggested that the pizza
could have caught fire if we hadn't been watching and that serious damage could
have resulted.
The repairman replaced the control
panel and assured me that it was made to work the way it did. When the control
panel goes out, the temperature is uncontrolled and goes up like it does in
self-cleaning mode. The oven door locks to avoid human burns -- to heck with the
pizza or whatever you have inside. I suggested that a fuse could prevent this
and was told that there is a fuse that would probably blow if the pizza had
ignited.
The lesson we learned here is not to leave an appliance
with an electronic control panel operating while we're out. This goes for the
washer, dryer, oven, range or whatever. If the control panel fails, the
appliance runs uncontrolled.
We hope our experience helps others realize the perils of electronic controls. We had never used the self-cleaning feature on the oven and joked that the oven decided it was time for a cleaning -- but this is not a joking matter. A house full of smoke, a pizza in the oven that can't be rescued and an appliance with a locked door creates a scary situation. I'm still a little reluctant to use the oven when I'm home alone.
See you soon!
