Question about Carrier Heating & Cooling
Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

I understand this to be a heat pump. Check your thermostat settings, and the filters. And make sure a breaker isn't tripped.

No this is not normal. You have a problem refered to as "short cycling". This is an indication of low refrigerant charge. You need to have the unit leak checked, repaired and recharged,

Hi, I would say to check for high voltage at the outdoor unit. You will have 24 volts from transformer on the secondary side of it, and high voltage on the primary side of the unit. @4volts are for all of the controls on the unit, contactor coil, all of the safetys, pressure switches high and low Ect. On a call for cooling, the stat sends power to the contactor coils, 24 volts to energize it and close the contacts and in turn starts the fan and compressor. Make sure you have high voltage at the unit. If not, check the main breaker, or the box mounted at the unit. Most will have 2 fuses in them that are behind a plastic cover. You can ohm them or just replace if your not sure. If you have power. If this is a split system central unit, check at the contactor for high voltage. If you have it, and it will not come on, you have to see if you are getting 24 volts to the contactor coil to pull in. If it does not, the problem is in the indoor unit unless this is a all in one outdoor unit. Please let me no, give me the details please.
