I (still) have an older Friedrich KM18J30 Window-mount Air Conditioner that used to work fine but doesn't run in fan or cool. Several forum members graciously offered their help troubleshooting... but I couldn't ever get it fixed. :violin:

So today, on a whim, I decide to measure the voltage at the outlet with a multi-meter; interestingly enough i found that the reading is questionable. Between the 2 hot pins measures low (102.7V AC) compared to the other rooms Air Conditioners outlets (they are 120V AC on the button) but between ground and either hot pin is 121V.
In the meantime, I could plug the suspect unit into one of the "other" outlets except that it is a big unit and weighs about 100lbs or so (again a guess) so maybe I'll dig around for an extension cord with the 250V NEMA-6 type connectors to rule the outlet in or out as the problem.
If it was the problem, I may go back to drinking :gulp:
after I kick myself in the butt a few times...:oops:

Problem solved, maybe a drink is in order; a change in fuse and now it works like a charm! the 2 bedroom AC's outlets are 120V so only require 1 20A fuse each but the living room is 220V so it has to have 2 20A fuses and there was a 15A and a 20A hence the low voltage.
