FIXED
I have a deal with this kind corporates sabotaging for 2-3 times a month fixing computers and monitors.
The circuit boards for many BRAND NEW household devices, PCs, Computer monitors, dehumidifiers etc. purposely designed to work a little bit after warranty period and die quietly
Heater EW7507EK fixing. (soldering required)
Step 1. Unscrew 2 screws on the bottom of the face side.
Step 2. Mark and Unplug 3 wires from heating element. Unscrew the metal cover from circuit board. Immediately you'll see small black cylinder (CAPACITOR 470mF x 35V). Retail cost about $1- $3
Check this - the top of this capacitor rounded, not flat. That is mean it was "quietly blowup" and electrolyte evaporate.
Step 3. solder new capacitor.
Enjoy

    Worked for Me I followed the instructions my capacitor was not rounded at the top but had a dark brown mess at the bottom by the terminals. Replaced the capacitor and buzz is gone and it works fine now. A extra plus, the screen you read had a film on it cleaned it while apart can now read screen without using a flash lite. THANK YOU

I have a kenwood model ew7507tek. powers on but only stays on for 6 seconds


I had two of these heaters and they both started to malfunction about the same time. The lights near the display window would not come on and there was a buzzing noise when it was plugged in. We determined that some kind of a relay inside was not working anymore. I got rid of both of these heaters and had to buy new ones. Seems like they lasted just past the warranty.

Fan heater blower on dimplex cadogan CGN 20 not working properly0 optimyst electric stove


Take it out and see if the fan wil turn by hand. It may have somethng obstructing it. The clicking is the motor overload. It wil burn out if it continues to keep clicking.

I bought a behringer bxl3000t yesterday and when I plug it to the wall it gives me a pretty big noise, even when the bass is not plugged in, If I turn the amp on without anything plugged and all the knobs...


Since you just bought this, exercise your warranty (assuming you bought this new). The amp probably will have a slight buzz with nothing connected... the question is how loud it is. If you can hear it loud at five feet, that is too much. If you bought this used, prepare to have it serviced at a shop.

I have a 110,000 btu reddy heater model r110. When i plug it in it just makes a buzzing noise? I am pretty good at fixing things so i took off the top, the fan on the motor turns freely when its not...


Steven, I thoroughly enjoyed your thorough explanation of what and how it e. Really, the best I have ever read, so far.

What may have happened it that the fan sensor may need readjusting or resetting. In case you have misplaced your Owners Manual, I have included a link to it that you can download and print for future reference. Pay particular attention to Pages 6 & 7, as well as the Troubleshoot Guide. If all else fails, get a bigger hammer! Just kidding. If you find you need any replacement parts, you can order them directly for www.masterdistributors.com

Owners Manual link below.

Hope this helps you solve the problem.

A loud intermitant buzzing coming from the back of the fridge


either the noise is coming form he ice maker fill valve( but if its of and still aking noise i doubt it. it also possible that the noise is coming from the compressor itself, overheating nad trying to restart in which case would give a slight "buzz" noise for 5secs or so then "click" off, and wait maybe 3 min to restart again. look for melted ice andperhaps your ice dream ont as hard as it should be???

Strange buzzing noise


Sounds like a bad filter cap in the power supply.when you change dimmer switch the buzz changes slightly because of a different power sraw on the power supply. If you are not versed in electronic repair. Get an Estimate. Or if unit is old get yourself a new one. Good Luck
