I have a controller for an electric throw blanket that I would like to repair, but I have no experience soldering on boards

You can see at bottom left a yellow box and a resistor. Something has burnt out in this area, and likely both will need to be replaced at a minimum

I would also need help identifying parts. The yellow box is embossed 'Tenta' and has printed on the side 'TC MEX/TENTAMKP 0.1 uf 275VAC' with some other markings obscured or damaged

Is this an achievable project?

Technically, since they are throughhole components and nothing specific (Fried resistor, 0,1nf capacitor and maybe a damaged thermal fuse.) this would be a great starter project for soldering. The issue is that those components failed becasue of something happening and unless you find out and fix what caused this you can change those components as many times as you want they will just blow again.

Thanks, as a learning exercise I am willing to have one good go before I turn the electronics into waste, but if they blow again that may be the end of it

I've been given an opportunity to ask 'genuineparts' where I should buy parts ๐Ÿ˜‰ (I'm in Australia)

I think DigiKEy and Mouser have Aussy sites where you would probably be able order the parts.
