Could be a number of things:
Could be as simple as having bad batteries in your thermostat “ if applicable” some thermostats do not have batteries.
Could have a programming error “ this could happen from a power surge or outage. In this case the thermostat would need to be reprogrammed.
Could have a bad thermostat.
Could have a short on the heat pump itself.
Could possibly be none of the above, though I would trouble shoot in this order.
After checking batteries and programming I would suggest contacting a trained HVAC technician to further diagnose the issue.
Testimonial: "Thank you for your assistance. I reset the breaker, took it off heating mode, put it back on heating mode, and the "waiting" was gone. Seems to be working fine. I appreciate your help."
Turn power off to outdoor unit for 1 min and turn back on. Monitor system for a few, sounds like it's off on protection but a reset will get it running for a few. Need service, likely refrigerant related.

FIRST YOUR OUTSIDE UNIT PROVIDES HEAT BY USING A REVERSING VALVE TO CHANGE THE REFRIGERANT FLOW.THERE IS NO HEAT STRIPS OUTSIDE SECOND YOUR EMERGENCY HEAT TURNS ON ELECTRIC ELEMENTS INSIDE YOUR AIRHANDLER UNIT.IT SOUNDS LIKE SOMEONE HAS WIRED YOUR UNIT WRONG OR HAS THE THERMOSTAT SET IMPROPERLY.WHEN THE HEAT PUMP CANNOT SATTISFY THE SETPOINT THE THERMOSTAT IS SUPPOSED TO TURN ON YOUR ELEC. HEAT UNTILL THE LOAD HAS BEEN REACHED AND THE HEAT PUMP CAN CONTINUE TO MAINTAIN IT.

I have a Honeywell heater i'll set my thermostat to 76 and ill turn on the heater and it would turn on... but when it get to 76 it turns off so when the temperature drops down and the heater clicks back on all i get is cold air .. it only works on the 1st time what to do ?

HAS THE COMPRESSOR CLUTCH CONTROL MODULE BEEN REPLACED? ANOTHER PROBLEM IS THE CLOSING COIL OF THE ELECTROMAGNETIC CLUTCH GOES OPEN IN HOT WEATHER, HAS THAT BEEN REPLACED.

The thermostat will not cut off the A/C until the thermometer reading gets to 76.
If there is not a heat source near/behind the thermostat which is causing the thermometer to read higher than actual room temperature, it sounds like the thermostat thermometer is out of calibration.
There are ways to calibrate it, but much to involved to go into here.
One solution is to just set the thermostat at 80, knowing that it's really set on 76.
Another solution is to replace the thermostat.
