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...

Hey Guys, not sure if this is correct part of forum to ask but, could anyone tell me what value this resistor is near the EC chip (ITE IT5571VQ-128) on a Lenovo Yoga Slim 6 14IRH8 motherboard please ?

(in the image , i have de-soldered the resistor and moved it up so its not making contact on both sides)

thanks in advance

Hi

I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode...

Hi everyone,

I’m repairing a PowerColor RX 5700 XT Dual Fan (not the Red Devil or Red Dragon model) with a burnt pin 5 on its 6-pin PCIe connector.
The previous owner had it repaired by a shop. They soldered an enameled wire to reconnect pin 5 to the current sense resistor (shunt).
The card wasn’t displaying anything after this fix.
When I inspected their work, I found that the sense resistor had fallen off after reheating the solder joint (likely due to damaged pads from resistor).
I tried to resolder it with a hot air station, but the resistor wouldn’t...

This dryer is several years old and has previously had a new motor cap. Currently it's behaving erratically - sometimes it finishes the cycle fine, other times it cuts out after a random period of time (just stops with no LEDs as if it has finished normally), and occasionally it trips the RCD. There's always steam coming off the clothes at the time it cuts out.

Going to pull it apart tomorrow, before I lob a new heating element at it is there anything else worth checking? It's £70 for a new heating element and the whole machine only cost £180 to begin with...

Cheers
