Re: Bad PSU shutting down my PC
Not necessarily during load, it happens usually a few minutes after boot. I will test the capacitors on the secondary side soon. Unfortunately I don't have a capacimeter, but I will try to borrow one.
Looking the pictures I would say it is the same PSU.

Re: Bad PSU shutting down my PC
If the PC is reseting during load, and heating the PSU temporarily fixes the issue, then capacitors are the most probable culprit. Just replace the capacitors on the secondary side with equvalent long life ones with at least 105°C rating. Manufacturer put a bunch of wires over them blocking the airflow and overheating them, causing them to prematurely fail.Leave a comment:

Re: Bad PSU shutting down my PC
Yeah I would still look for bad caps. It sounds like that's what the issue is. Teapo has a high likelihood of failing without showing symptoms.Leave a comment:

Re: Bad PSU shutting down my PC
After 4 days away home, I turned on my PC yesterday and after several hours running it didn't turn off. I didn't use a hair dryer on PSU, I only turned it on and no problems until now.
Maybe after 4 days of resting my PSU fixed itself
Should I still look for bad caps on it?
Edit: It did shut down a few minutes after I post here.

Nope
But an esr meter is an excellent investment. You can find on ebay at very low price.Leave a comment:

Re: Bad PSU shutting down my PC
Yes, my bad. This PSU is maded by CWT, based on a CWT design.
I will, as soon as it shut down again. It is working right now, after I used a hair dryer on it for a 3-4 minutes. But I did try to turn on my PC before without using hair dryer and it turned off after 5 minutes.Please post pictures of your actual PSU in some different angelsLeave a comment:

Hello everyone!
I dropped a hair dryer in the water after using it. I pulled it out fast but it was still hot, plugged in the mains and switched off. Still in warranty but the shop I bought it is in another country. The local repair shops asked 50-60 eur for repair. The dryer cost 60 so I was thinking maybe there is smthng I could do to fix it my self. I took it apart but I reached the point that I cant understand what the problem might be. I dont have electronics knowledge. Just some basic electrical.
There are 3 leds that are blinking when is plugged in but it does... -
My Bosch NEXXT 500 dryer quit today, press start nothing happens and the start button just keeps blinking. Not cool. Reset the dryer, same thing.
Even so the buttons feel good, my problem was the start button smd tactile switch on the PCB. Cleaned the switch with alcohol followed with Deoxit and the sucker runs like a champ again.
I like these easy evening fixes!

Just wondering if anyone has successfully attempted a re-gas on a heat pump tumble dryer.
The dryer currently in question runs on R134a.
The dryer has been completely stripped down/cleaned/tested and re-assembled however there is no heating/cooling effect so working on the assumption it requires re-gassing. Of course, its likely theres a leak which would require soldering or even the possibility that the compressor has an internal fault even though it is running.
I was thinking of getting a car aircon regas kit or probably easier but slightly dearer an hvac... -
Hello,
I'm helping my brother to fix his Blomberg laundry dryer. He called a repair guy to have a look and the repair guy said the control board is faulty. They said the replacement board costs $400. Too expensive! 😨 My brother asks me to take a look. He has checked the door switch and thermal fuse, etc., and those seems fine.
After plugged to mains, there is no display. There is just a clicking sound from the buzzer, like one click per second. No other response.
I suspect the firmware inside the MCU (ATMEGA64A) got corrupted. Can someone in this forum by any chance provide... -
Patient is a Maytag/Whirlpool/Kenmore clothes dryer. Not sure of exact model, doesn't matter. All boards are out of production.
Specific problem is a Maytag 8544799 / WP8544799 motor-control board, aka Diehl Controls 708879-05. Customer states the board "doesn't work, motor doesn't run". Not sure how the repairman made that assessment, or if it's even accurate. He can't get replacement boards, and the owner decided to buy a new dryer, so whether this board is the problem is speculation on his part. Again, doesn't matter.
I've been over the board looking for...
