I have two Lidl LD6273 Auriol units with DCF77 radio for time update.
I really like the idea but the cheap moisture sensor(guess HR202L) inaccuracies make the device unreliable. Also not clear why indoor and outdoor unit sensors being same type doesn't match. For example I place both units on same table and indoor unit shows 23% humidity while outdoor sensor shows 39%. What I found out is that I get better readings if cleaning the solder points of sensor inside with isopropyl alcohol.
Looking for replacement sensor which I could solder in place of [URL="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiC0Zi17ceJAxW7EhAIHXnxItQQFnoECBkQAQ&url=https%3A%2F%2Fwww.makerhero.com%2Fimg%2Ffiles%2Fdownload%2FHR202L-Datasheet.pdf&usg=AOvVaw3Ii9ppx16LrqbLtUtAohVS&opi=89978449"]HR202L...

Re: Help identify varistor
Thanks.
The previous converter failed so maybe took this on the way. -

Re: Help identify varistor
It is from Galmet wood pellet boiler controller.
Apparently it was left switched on all summer in tripped state. When it trips the LED backlight is not visible so looks switched off. Wood pellet boilers this year are very popular in our region.Leave a comment:

Re: Help identify varistor
This is fuse?

Re: Help identify varistor
Seems it is not the problem. I got voltage drop on input so the converter shuts off after some 5 minutes looking for cause.Leave a comment:

Double checked yes it is parallel to AC.Leave a comment:

Re: Help identify varistor
So this is not inrush current limiter?
How to verify if it is not bad?Leave a comment:

Re: Bosch AL 1830 CV(AL1830CV) blown fuse
Replaced FET, R7 resistor, fuse and it is still short. Blew fuse and R1 thermistor(8S150L).
Need to look further.
You where right it was not so easy.
edit: two of IN4007R(or 1N4007 ?) diodes are shorted. Should I replace them all with UF4007?...Last edited by otoluk; 10-10-2022, 12:19 PM.Leave a comment:

Re: Bosch AL 1830 CV(AL1830CV) blown fuse
V5 Mosfet(ST P6NK90Z)is short on all pins.
Mains cap(C2) is ok but while others are FZE, FZK and GF series this is noname Acon.
Inrush limiter has same pcb coating which is cracked but part is ok.
Thanks this was unusual as also it is isolated from V5 by
plastic gasket. What for as it limits heat transfer?...Last edited by otoluk; 06-09-2021, 01:31 PM.Leave a comment:

Have to also decode resistor near V5Leave a comment:

Fuse blew with nice sound effects. Seems need to replace fuse and resistor. No schematic is available.
Not sure what have caused this will try to replace 400v cap, resistor and fuse.Another victim of planned obsolescence.
