My fridge/freezer broke down and the repair guy replaced the circuit board then said that a component always burnt out on the boards:
BZV90C16 - A Phillips Voltage regulator diode. (Plastic surface mounted package (SOT223 (SC-73)) with increased heatsink - 4 leads)
I've googled this and appear only to be able to buy it in large quantities. Does anybody know where I can buy a few for future repairs.
(David Johnson, on a forum, says I can use a 1N5353 zener diode (two leads) soldered onto the correct pads. The BZV90C16 has four leads. Whilst the outer two pins on the bottom are soldered onto the same contact this still leaves the middle bottom and the top ones.)
