Air Conditioning: LCD backlight toevoegen aan remote control

Mon, 03 Aug 2020 15:07:26 -0700

Ik wil LCD backlight toevoegen aan een bestaande remote control (daikin ARC433A) zonder backlight. Ik heb 2x1,5V AAA en weinig plaats beschikbaar. Zou enkel licht willen als ik op een knop van de remote control duw (‘s nachts in bed). Ik ben op zoek naar een link die mij in de goede richting zet.

HVAC: hoe kan ik een thermostaatkraan vervangen

Wed, 19 Nov 2014 20:57:44 -0700

LS,

Ik wil de thermostaatkraan van een grohe pharo lift douchepaneel vervangen.

Ik zit al een poosje te googlen naar een oplossing maar het model wat ik zoek schijnt verouderd te zijn en ik kan hier niets over vinden?

English:

I want to replace the thermostat with a Grohe shower panel pharo lift.

I'm already googling for a while for a solution but the model I seem to find are outdated and I can not find anything about this?

My dehumidifier has not been collecting water in the drawer. I have just taken the filter off to have a look and noticed water in the back. Is there anything I can do about this? I can’t find any blockages to the water to drawer.

Dyson AM07 Tower Fan: faulty fan now board dead

Thu, 02 Jul 2026 03:51:16 -0700

So i have just replaced the oscillating motor and the x2 cap to fix the side to side movement and stop it happening when it's off! the main fan motor was a bit noisy, so i decided to take the impeller off the motor and clean and lube the bearings...bad idea! the impeller ended up breaking the locating lugs off the bottom of it, and after all the messing around, when i turned it all back on, the motor was really unhappy, causing surges and then cutting out completely. tested the fan from a known good machine and it worked for half an hour continuously at 10 without any issue...

I managed to source a second hand unit from a dyson repair shop nearby, and it arrived today - plugged it in, the display came on, motor did nothing...seconds later the screen went dark and nothing worked since. i've since tested the motor, and it seems to have a short/very low resistance between the case and W1 phase wire - obviously it's sent 300v upstream and done some damage!

I've checked the fuse, all the 0ohm resistors i can find, and run through a load of testing with the help of AI to prove the buck regulator, the mosfets and the driver ICs all seem to be behaving as expected. however, after tracing U2 (5v regulator), it seems to have a direct short to ground on 2 pins. from what i can find, it appears pin 1 is output (apart from anywhere else, it supplied voltage to the screen), pin 2 gnd and ping 3 input - which appears to have a direct connection to the buck regulator IC output. thinking the 5v regulator had gone short, i pulled it.....and still have the short. then i removed cap c7 to make sure that wasn't shorting....it wasn't either.

Literally tearing my hair out now (shop said they wouldn't replace the damaged board, but have agreed a 50/50 split on a new board if i have to; but I would rather fix this.

Can anyone offer any advice? any common failures when the motors go short?

Thanks all!
