I live in a rural area, where we have frequent power outages. Because of this, the existing airhandler (heatpump/separate airhandler) would "short-cycle" or go on-off-on-off (etc) in rapid succession. This action drives me up the wall hearing that sound and visualizing the commutator being "burnt", each time that it would happen. (Apparently, there was a delay timer built in to the Honeywell thermostat to protect the heatpump compressor) Thanks to the advice of Ed Imeduc, Bloodstone, GregH, Jim-Connor and TigerDunes, of this forum, I'm having installed a Trane XL16i dual stage heatpump with a matching variable-speed airhandler. I understand that the new heatpump is protected by a built-in "anti-restart timer". The QUESTION...Is there any sort of anti-restart/delay timer" that can be installed to protect the new variable-speed (airhandler) blower motor, to minimize any damage done during a short-cycling event. Many thanks to you all. TranquilAcres

The problem I have I believe is in the outdoor unit. Sometimes the unit will not come on when the call for cooling is sent. At first I thought it was a wiring problem but after checking I have power at the contactor and all the proper terminals coming from the thermostat. Unit will always come on when the contactor is manually pushed in. The unit does not trip any circuit breakers and never looses power. I'm starting to think that maybe the defrost board in the outside unit overheating or something. I don't know of any way to check the board though. The outside unit will come on, most of the time, if the whole unit is switched off at the thermostat and allowed to sit all day without running it will come on in the evening. Any help with diagnosing this would be greatly appreciated. Thank You
