Question about Mitsubishi MS12TN Air Conditioner
I have a wall mounted unit in my office that runs well for half hour then stops, the operation light flashes once this happens and there is no airflow, ive had an engineer look at it and he said when he put the gauges on it ( the outdoor unit)was running at 8 bar on the low side and was running at 8 bar but the high pressure side would get up to a very high pressure but then it cuts out,any ideas please?!?
This can happen in cold humid weather, when you use heating mode and the outside unit freezes up. All my split-type airconditioners do that occasionally when the weather is like that. The inside fan stops for some 10 minutes with light flashing, then it picks up again after the outside unit warmed up.

Hello, It depends what refrigerant the system is on but if it tripping out on HP it could be overcharged with gas or a problem with the outside condesor fan.
