Is this soldered controller repairable by an amateur? (lemmy.zip)

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?

It’s a “safety capacitor” used across AC, similar to a Y cap, they have a known failure mode that is designed to not cause fire.
