Danfoss 103 timer is making a constant buzzing noise!!...everything's works fine but I want to stop this buzzing noise. Any actions I should take or advice would be much appreciated. Thanks.

Transformers make noise..
If transformer is buzzing, then it has probably gone bad.

Hi,

Is you unit hooked up to water because if your unit has an ice maker and not hooked up to water currently, the ice maker will call for water about every 45 mins and cause this noise. To stop this action, lift the bail arm to the off position to avoid or stop this from occurring.
I hope this helps.

The thermal element that gets red hot and lights the pilot (assuming you have pilot flame) is cracked or broken. It is possible to light with a match but a nuisance.

try cleaning vents/drain holes in whole unit this should allow more air to flow.also when did you last manually defrost whole unit.....

Had this happen, was advised that it is most likely the clock board, and that there are NO internal parts available for the XL-44. Turned off the power at the breaker box, pulled the two upper back panels off (the bottom one must be removed first, as the top one has a difficult-to-access sheet metal screw on the bottom inside at either end), then just pulled the common neutral lead (white wire that daisy-chains along the various electrical bits) from the E2 terminal on the bottom left side of the clock board. Applied some heat shrink tubing to the now-disconnected neutral lead to keep it from shorting, and buttoned up everything. The clock is dead, but everything else works just fine and there's no annoying buzzing sound any more.

that is the sign of a bad dryer motor-sorry-mike

Bad timer

i don't know jennair specifically being from england.
however, there is often a fan inside the back panel and the noise you heard was the fan hitting ice. the reason now not heard and fridge not working may be that the ice has built up so much the fan is jammed

I took the top of range apart to see if I could unplug the buzzer. Wasn't sure which wire it was so I just unplugged the bottom four wires one at a time.....don't really know what it did but it stopped buzzing and all the wires are plugged back in. Only thing I can think of it must have re-set something cause it works fine now

I have a GE counter top microwave oven. When the oven starts cooking (the magnetron turns on) the oven makes a harsh buzzing noise. What is wrong and what should be done?
