DIY repair – my microwave, an integral part of my espresso making process (milk steamers are fucking annoying) went on the blink– the magnetron was always-on except went the door was open.
With the choice in front of me being to drop $350 for a new convection microwave, it wasn't going to hurt to open the thing up and see if there was any chance of fixing it myself… and behold, the magnetron was controlled by a relay, making me think immediately that if it were stuck or burnt-out, it would explain the fault.
Controller board out; desoldered the relay; and tested it– and it worked. Crap, probably something less obvious was at fault. Resoldered the relay and reassembled the microwave. There was still the idea to test if it could have been a dry solder joint which the resoldering would've fixed– and luckily the microwave started working!
Awesomesauce. The $180 desoldering station has saved me hundreds of dollars again.
