you need to format the HD. The sudden power outage is the reason the unit is freezing. As a matter of fact, the HD is the cause of the freeze. The HD has not been able to recover from the sudden power outage.
Format the HD and hopefully the unit should be back to normal.
But if unit is not in order after formatting the HD, please let me know for further direction.
Hi, is this furnace a free standing unit or a full size electric heater? You can try turning off the main power to this heater for 5 or so minutes and back on again. You may have lost a internal stat of some kind. Try what I said and if nothing changes, send me the model and serial number so I can check into this further. If it stopped at 60, it should be alright at 65. The thermostat may have burned out. I don't know this yet but let me know what happens. Shastalaker7
In all probability that Power Outage caused a massive Spike or Surge on your power line. This has affected this unit. It doesn't take much to cause this type of thing and is quite common. It may be repairable, however these days buying a new one is often a better option. If you do go the repair route, go to a reputable place, & please ensure you get a firm "Quote" not an "Estimate" for repair.
HI. This will occur when a surge has entered the unit, due to the power outage. Normally, there will be a power surge when the power is re-introduced to the home circuits after a brief outage. This will damage most unprotected electronics in this situation. The most vulnerable area in the unit will be the main control board. I would advise to try a hard rest. You can initiate this by simply shutting down the appropriate circuit breaker, or unplugging the unit for 5 minutes. Once the 5 minutes have passed, kindly re- introduce power to the unit, and try to run a baking cycle. If the word stop, or PF illuminates on the display, this will confirm that the surge has damaged the board. It must be replaced, in this case.
