This is a product that heats up and dries wet ski boots,
the board powers 2 big heat guns I guess with programmed cycle
times. No SM or schematic of course.
Main bridge was shorted, seems directly fed from 115V line power.
Replaced the bridge with a thru hole type and hooked up with a variac to power.
At one point the panel lit up with power, then there was a snap
and thought I saw sparks from the 2 large heat guns in the chassis,
then dead. Fuse blown - bridge shorted again.
Seems like they are using a IC on the boards
to handle the switching side of the SMPS, its a Viper35SP
made by St electronics:

Looks like its obsolete / NLA from what I can see so far. Some on Ebay for purchase.
I think the IC runs straight from the line power, rated at 800V.
Should I try the support components around the IC or try replacing the IC?
I am thinking the heat buildup perhaps caused the smd caps to dry out?
Sziasztok!
Szétszedtem a szomszédom boyler-ét, mert csöpögött belőle a viz, Akkor láttam, amit még sosem láttam, a fűtőszál "kiégette" a hőm. szondának a vezető csövét, de hogy, hogy azt el sem tudom képzeli, mert a fűtőszál nem lyukas, csak kicsit kormos volt, de sértetlen, a cső pedig kiégett, és ráadásul 3helyen!
4hónapja volt a boyler vizkövezve, és akkor lett benne minden újra cserélve.
Szerintetek mi történhetett???
