I have a MHI SRK63ZEA-S or 71 or 80 not sure as the manual is for all three.

Just turned it on and it is dead!! Remote is fine, new batteries, checked the outside elect box and the special switch for the aircond is still on and checked the on/off switch under the inside split as well.Just D E A D. It was last used maybe 2 months ago for heating. It is 3 years old and hardly used.

Could this be electrical or compresser and such?

One guy told me to call a fridge mech not an air cond guy.

@lonnieleevideo I am really not sure whats wrong with it, it could be PSU failure, indoor unit not sending the signal to the outdoor unit, or somthing like that.

A lot of modern stuff is garbage because of those switching mode inverter type power supplies, in theory they should work well and last, in practice they build them using bad designs, with cheap parts with borderline voltage ratings and tolerances. I found that out with a Panasonic Inverter microwave, started blowing fuses and then died, found out they are made out of unrepairable junk, oddly enough from an Aussie website. Engineers just don't understand the KISS principle anymore

@OlegKostoglatov yeah my Panasonic inverter microwave is less than 3 years old and the turntable control freaks out randomly, usually stops or gets confused about which direction it wants to go.

Its getting to the point where this 'energy saving' inverter technology is costing more energy/money because it fails way too soon!

how many bridge rectifiers do u have ? Im low on bridge rectifiers :/

[Aussie50]

@TheElectricnoob I have a few from various appliances, dunno how good they are in terms of current handling tho.

those choke coils have nice big ferrite cores, good for making eletronics projects that use current transformers. you should make a large joule thief that runs a few cfls on a AA battery.

@Aussie50 If its those square ones with a hole in the middle and 4 spade connectors, their most likely 16-25A and 500-1000V.

@Aussie50 you can look up the datasheets for bridge rectifiers on alldatasheet . com

just put the model number in there at the top (like KBU805G, FL406 ....)

one of the few websites with free datasheets (none of that "pay 15bucks to get access" bullshit)

@Aussie50 I don't know if it saves anything even if it is working right, I think the main motivation was to save on copper in the transformer, but when you add up the parts to build an inverter supply it likely isn't any cheaper. As you say if the microwave dies prematurely it's not saving energy or materials, in my case the high voltage supply to the magnetron decided to die, the strange part was that while it was going out it smelled of ozone inside but I couldn't find any evidence of arcing.
