Hi, after a power outage, normally as power comes back in, it's a little bit high than normal. With a dead set that you got, it would probably be the control transformer. The primary could have been burn by a spike voltage.
(sudden rise in voltage above normal).
Or it's likely to be a fuse problem. Check first the fuse, if the fuse is o.k, then it would be the transformer.

Take care

Had a short power outage now the unit will not run. breaker ok and 234 volts to outside unit but inside unit will not come on. is there a reset or something


Try turning the unit off at thye meter box or the isolator switch out next to the outdoor unit of the air con. Leave off for 15 minutes and then switch back on again. Some Air cons get screwed up with power surges... Leaving off at the mains for a while often resets them. If the air con was running at the time the power went off, it may have damaged one of the electronic boards... Do you get any flashing lights or displays showing what could be an error code ??
