My MSH 024 Air Conditioner keeps tripping off at the mains switch
When switched back on at the mains it goes for a minute then stops again. The unit is in a shop 25square metres and runs at 21'c. Ive tried switching everything else off (ie before openning), but the same thing happens. Ive had the unit 4 years, without any problems, it just started a couple of days ago. My clients and staff are complaining. Can you help

FIRST TRY TO CHECK THE CIRCUIT BREAK THAT IS CONNECT TO THAT AIR CONDITION, USUALLY IS A 30 AMPS OR 40 AMPS CAPACITY, MAYBE IS BELOW THE AIR CONDITION CAPACITY AND OVERHEAT THE BREAK, OTHER WISE UR SHOULD CALL A TECHNICIAN TO CHECK THE COMPRESSOR AND THE COIL OF THE CONTACTOR

It's going thru the defrost cycle. Once that ends, the unit should restart. If it doesn't wait until 3 minutes have elapsed, after the stop light goes out and restart the unit. If that fails, turn the Master ON/OFF Switch to OFF & unplug the unit. Wait 15 minutes, plug the unit back in and turn the Master ON/OFF Switch to ON. The unit should have reverted back to the original factory settings. If so, reset the controls as you like.
I hope this helped you and thanks for choosing FixYa.
Hi I have Mitsubishi split unit which is 5 years old. when turn heat mode for 30 deg C on the remote condesing unit runs for about 6 minuts and stops. what would be the Technical problem ?Thanks an Apprentice.
There is a limit switch tripped somewhere. it is either the main limit in the firewall orthe limit switch on the small fan (inducer) that is tripped some of these are manual reset try pushing the button in and see if that stops it.
turn the unit off at the main circuit breaker or isolating switch, to reset the unit it has tripped out on its high pressure safety. to stop this problem happening on 42 plus days hose down outdoor coil with water
Every air conditioner has a motor called a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself. When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner.
If the compressor turns off and won?t come back on during a very hot day, the unit may have built up a high "head" pressure and the high-pressure limit switch may have tripped. This is usually located right inside the access panel on the compressor unit. Simply push the button to return it to operation.
If your central air conditioner doesn't go on automatically:
1) Be sure the thermostat is set to "cool" and set below room temperature.
2) A central air conditioner should be on a dedicated 240-volt circuit; check the main electrical panel and any secondary circuit panels for a tripped breaker or blown fuse. If you find the problem here, reset the breaker or replace the fuse.
3) Make sure the furnace power switch is turned on and that the outdoor condenser's power switch, mounted on the outdoor unit, hasn't been shut off. Also be sure the 240-volt disconnect next to the compressor (in a metal box, usually mounted on the house wall) hasn't been shut off.
4) Turn off the power to the air conditioner and check the thermostat.
5) Remove the thermostat's cover and unscrew the wire from the Y terminal.
6) Turn the power back on.
7) Holding the wire by its insulation, touch the bare end to the R terminal and hold it there for about 2 minutes. If the compressor kicks on, the thermostat is faulty; replace it or call an air conditioning technician. If the compressor doesn't go on when you hold the two wires together, turn the power back off and call a service technician.
