Should the heat strips come on when heat pump is in defrost mode? When heat pump goes into defrost mode, I only get cold air coming out of the vents. I've looked on-line and a lot of sites say the heat strips should come on and warm air should be coming from the vents. Is this right? If warm air is supposed to come out, any idea why my unit only has cold air coming from it? Thank you in advance.

If you have a new system there could be a wiring problem.Otherwise I would suggest that you call a service tech to check why the back up heat isnt working.Your heat pump will run alot more often if the electric heat doesnt work.If you know how to operate an amp meter and have one handy, then you check to see if the electric heat is working by turning up the thermostat five degrees or so.The amp draw should well exceed that of the blower motor.If none of that made any sense,then call a technician...Good luck...

cheybay,
let us know the name, and model of the system, how old is it, type of thermostat, has any thing been serviced on the system, size of the system and space that it is to control, remember, we are not there at your home to figure out the problem, so the more info that is supplied the more able we may be able to help you diy. carrier is correct in a way to check out if the strips are lighting up, but i would like a little more history on the system before you start messing around high voltage. i am leaning toward a low voltage control problem. let us know what you have, we post back really quick.

I have a Carrier Heat Pump ouside, model # 38YCC060300, not sure of age; a Payne air handler (in attic), model # PF1MNB060, less than a year old; a Ritetemp thermostat, model 8050C, less than a year old. The air handler was just installed around September and I installed the thermostat a month later. I'm including the wiring for the thermostat just in case. I don't know the size of the unit, but it heats/cools approximately 2,800 square feet (two stories).

You have a 5 ton unit.Sounds to me like you may have some wireing issues.When the unit goes into defrost then 24 volts is suposed to be sent on w1 from the heat pump to the air handler.Thats how the electric heat is made to run in defrost.Check for 24 volts at the air handler.Check the heat sequencers .Is the first bank of electric heat getting a call?I dont know your ability in electricity.You may need to call whom ever installed the system if you cant check things out with a meter.Good luck...
