Re: error code of 6 flashing light on circuit board,
There appears to be a short in the unit. Not sure where. The power to the fan is not interrupted completly when the fan shuts down, still feeding voltage to the fan, keeping it running slow. Before checking the wiring, please turn off power first.

It always helps to add the model number of the item you want help on. However if it's like the newer units, the fan operates whenever the heater wall has reached a high enough temperature and shuts off when the heater cools off. It is not wired into your thermostat or electrically wired to the heater. It does that with a temperature driven fan switch in a little junction box mounted to the heater. Normally when that box gets hot because the heater is on the fan comes on, when it cools off the fan goes off. The junction box will have an ac cord coming out of it. If this fan switch junction box is not properly mounted it could be getting cooled off when the fan starts and then shuts itself off. After it heats up again it starts the fan. The other possibility is the temperature based fan switch is failing and needs replacement. See link.
when you have that problem , almost all the time is the heater core clogged , you can have the engine running until reach normal temperature and touch both heater hoses at the fire wall, if one is hot and the other is not them the problen is your heater core.
No the fan out side is for a condensing unit and compressor. The compressor should not run with the heat. I am almost positive that if this is not a heat pump that the compressor unit should not be running.
Turn off power, if this is a complete outdoor unit, remove the blower door Turn Unit back on see if the blower motor is working. If belt driven belt is loose or off, if direct drive and the fan is not working, its possible the capacitor is bad or fan is bad.
If fan is operating, then either a damper is closed, something is obstructing the duct or it is at to low
it sounds like the low temp limit switch, the one that cools the furnace down with the burner off and the thermostat open, when it cools to a point the fan stops, the other switch in burner area turns burner off/on, hope this helps
ok...where to start.lol ....the thermostat is just a switch.It will tell the unit to run or not run.if you measure the temp with the heatpump running,the air is warmer than 68 but it feels cool to you because your body is 98.6.The unit will run more often and for longer periods when the temperature drops outside for a few reasons.First,your house has more of a load to heat,meaning you have more heat loss because of the difference in temperatures outside and inside.Second,your heat pump pulls heat from the outside air.The colder the air outside,the less btu's for it to pull.If you have anymore questions firstname.lastname@example.org Hope this helps,Dave
