Hi All.
I've a large Mitsu unit that displays the following symptoms.
1. Indoor unit, remote etc working fine
2. Outdoor unit goes to turn on and draws so much current that brown out occurs
3. Trys to do this 3 times without success and throws up 5 flash error code
4. Sometimes, the draw is enough to trip the circut braker
5. light humming from outdoor unit and a straining sound when compressor tries to kick in.
I figured it was a bad start run capacitor so I went ahead and replaced it for an identical spec unit.
- Now the when the compressor goes to turn on, it trips the circut breaker every time.
- I can still hear a humming from the outdoor when off / but power connected
- The dicer board and all cables / joins etc are clean and good condition
- I've checked all contacts are secure and eveything is tight / good contact
I am thinking the compressor is actually stuck / wearing out but am not sure. The buzzing I can hear makes me think it is still an electrical fault so I'm not sure what to investigate next.
Should I just order a Superboost or similar type item to give the compressor that bit of extra kick, or should I be following a totally different path?
Thanks heaps
Puff
