that's probably a dual-mosfet... -
do the ajustable modules go down under a volt?
in a stable way i mean.Leave a comment:

is a special conductive glue.
we had a thread about it years ago when samsung tv's started failing in large numbers.
there was also a thread at eevblog about the displays in fluke scopemeters.
i think you can use heat to re-bond it but people did that on the pcb end - probably more difficult on the glass part...Leave a comment:

most dryers use the same motor for the drum and the air circulation fan.
if that doesnt run the heater will get too hot and that will get detected.
if it's an electric heater anyway, gas ones must have a heat exchanger and more safety devices....Leave a comment:

the current is limited by the transformer.
using a bigger fet probably wont change anything....Leave a comment:

parallel lamps is correct,
most equipment has the wattage or amps marked on the back - going double that to allow for inrush is probably fine....Leave a comment:

i think he is refering to bypassing the relay....Leave a comment:

most likely if you have 2 with burned pads the relay is burning inside and the heat from that is burning the pad.
it needs a better quality ore higher current relay....Leave a comment:

F1,2 and 3 look like they are in parallel so if F3 meters open F2 will be the same.
to remove it put some solder on both ends and heat it from the center so both ends melt - then slide it off the pads...Leave a comment:

use a larger wattage lamp, the psu isnt getting enough power to start up.
made worse btw if the device has active PFC in it.Leave a comment:

remove the relay and sand/ file the contact and check the case isnt melted around it....Leave a comment:

that could have been caused by bad sofering OR bad relay contacts.
either way, you have to remove the relay,clean the board and ideally fit a new not-cooked relay.
otherwise the control board will know the motor isnt being powered....Leave a comment:

post a good picture of the primary side of the board....Leave a comment:

wtf happened to the radiator fins?...Leave a comment:

fuma 3 fans can move more air if they need to.
both are huge - thats why i switched to AIO water cooling....Leave a comment:

well if it's AMD the the bios isnt "Israel-Inside" anyway.
i dont dont know exactly what AGESA is but i'm sure it's less insidious than the Intel Management Engine and it's associated secret microcontroller hiding in the bridge i.c....Leave a comment:

resistor colours dont include pink.
and resistors dont burn for no reason - you have a bigger issue to find.Leave a comment:
