Enigma SLR61-GW. System runs for about 30 mins and then shuts down and a status light blinks 4 times.

Check web site for significance of the four flashes. Could be that it is overheating and shutting down due to excessive current consumption.

Witch blower is running, the inducer or the systems blower?
System blower could mean the the high limit is opening and shutting down the systems gas train, I would check this out first.

The other problem could be with the pressure switch for the gas train, it is supplied from the inducer motor, check to see if it is operating fully.

HSI boards do go from time to time, this sounds more like a system control problem.

Try cleaning the condenser coil.

Check if the high pressure switch is open and check discharge pressure. If it is open remove some freon from the unit.

Hi,
The unit is usually low on freon when this happens...the machine will over ride the freeze stat and the low pressure control for five minutes and then shut down...
Have a tech. check the system for leaks and repair them.
Then recharge the system and you'll be good to go...

Please write how many times blinking and with an interval. Depends upon it, we can give solution.

Normally, blinking 5 times means for drain motor malfunctioning. Check drainline, oif blocked clean it. If drain motor not working, replace it.
If blinking 2 times, Indoor room air thermistor defective replace.

Thanks.

when we start the AC indoor working and out door unit compressor working but fan motor not working and indoor timer light blinking

Looks like thermistor problem. take service help.

I have a MH050FX A2 that is two head unit and they run only one at a time, when I turn both on, one will shut down. I get an error code of E2 01 with a, I beleive correction code of U C8. Can you help me with a diagnosis??

This is pure conjecture but I think the cooling fan has failed or is running slow.
Check to see if it can still be heard.

This system seems to be a bit weak on reliability.
