My Jun Air 6 X 25 stopped working
by Throstur Vidisson
(Reykjavik Iceland)
My 1987 Jun Air 6 X 25 does not work any more. The symptoms are as follows.
At some point I got smoke that seemed to originate in, or close to the Terminal Box. The Terminal Box houses the Starting Relay and some small device that I think is a Motor Protection device.
After this the compressor seems to try to start, it ticks once or twice when I power it up, but can´t quite make it.
I have considerable experience in dealing with mechanical and electrical repair but it seems to be difficult to find support for repairing Jun Air on the Internet.
What I have done so far is that I measured the big capacitor with a capacitor meter and it is within specs.
I took the Terminal Box apart and could not see anything wrong, nothing burned or loose and no bad smell anywhere. and took off the top of the motor and it is full of clean oil and the crankshaft is turning freely.
The problem is that I don´t know how the Starting Relay should test/measure and if the small device that I think is a Motor Protection device is possible to test.
So I´m a bit stuck here and all tips and help would be greatly appreciated.
Throstur:
Not sure how old this is, but anyone looking for info –
The specs and diagrams for model 3 and 6 and a few others are listed as model 3 on the web page. The drawings start on page 29.
looks like starter relay
to be sour you can test your compressor by helping to run it manually
Hello,
Same problem on mine, smoke was coming out of the air inlet. Turns out piston is siezed !
