Either you have a safety switch tripped or a faulty circuit board. Test all of the limit and roll-out switches, they should all read closed with an ohm meter.

Control fuses only blow with a 24 volt problem. Make sure that you replace it with a fuse NO LARGER than 5 amps.You could have a thermostat wire pinched or some wire touching the cabinet inside the unit, but it is a 24 volt problem.

Sounds like you may have a dirty flame sensor. Try cleaning it with steel wool or Emory cloth.

Believe that is hot surface it should relight itself. turn the power off & back on, the power outage could have messed with the circuit board

Hi Brandon , seems like you have a dirty flame sensor . Clean the sensor if that doesn't work check for continuity in the high limit fuse .

Just a guess unless you read from a paper on the inside what 4 flashes mean but usually it's the igniter

This is a small furnace is your home about 1,000 sf? If your home is a 2000 sf home it may be too small and therefore low air flow. Otherwise you can try putting high speed black wire to heat on the circuit board. Or you have a main duct down somewhere.

What is -the outside?
Heat pump, gas, electric heat combination?
You may need to back track, double check the Honeywell configuration jumper or software settings for your type of heating used.

There should be a fan symbol on your remote control. In the "mode" control, there should be the following options.. Heat, cool, Auto and fan. If you select fan, only the fan will run. No heating or cooling.

Check voltage in , there could be one side of breaker burned causing only one side to come through. This happens on older main breakers frequently which messes up whole house.

How are you determining that one cold and one warm? If this is in fact the case you have a blockage in the coil or a compressor that is down provided this is a multi compressor unit.

I'm leaning 2 directions, one is that your tstat is sensing your heatpump can not keep up with the load. Therefore bringing on heat strips or two, you have a cycles per hour limit set for compressor heating and your machine is cycling too often.
