Our on/off switch is broken, how to fix

Probably a burnt out element. See this video if you want to fix it

The black part behind the knob is a 14 step code switch.
It is easily replaceable. You may send me a message if you need a spare.

Turn off the power to the appliance. Squirt WD40 liberally all round the knob, trying to get it in behind it. Wiggle the knob and press it down and up if possible to let the WD40 oil work in to the dirty or stuck joints. Leave for a few hours and wiggle it again to see if its loosened up.

In order for the element to stay on, the oven switch must be broken. No details are provided, but if your oven is like most, you have an Oven Selector knob for ~bake, broil, clean and another knob for Temperature selection.

Look at your Oven Selector knob closely to make sure it is not slipping on the shaft. It may be as simple as the knob being broken, and even though you are turning it to the Off position, the switch may still be on. If the knob is indeed turning the switch shaft, then it is most likely the switch stuck in the own position. Thanks for using FixYa.

You will need to get a replacement knob for it as either the spring clip or plastic has broken.

Some Bernina models have a three application switch.

Light, light and power pedal and just the power pedal.

Inside the machine, at the back of the tower is a circuit board. It could be the contact or wire is broken.

HI,and a merry Xmas.
Yes it is repairable, it is going to be one of two things.

1--the control knob is cracked or broken causing it to twist round without turning the control.
2--the spindle on the control is broken or loose inside the switch.
Pull the knob off, and see if yopu can turn the switch on and off with a pair of grips or pliers.
This way it will enable you tell if it is just the knob or the switch that is faulty.
Good luck.

Please leave feedback for my suggested solution.

Hi Your Problem need an expert Technician, this Aiwa stereo has the digital type volume control that gives pulses to the cpu to make volume up / Down. Solution to be fixed by a technician: - Remove the volume from the front board, disassemble it and clean the conductive parts inside it then reassemble back and check. Good Luck Toufic G. Malek
