It could be your capacitor. I had a fan capacitor go out on one of my 3 units last year and it cost close to $300 for an AC company to come out and fix it. I watched them fix it and it's something that you can do yourself if you know what you're doing and are careful to hook it up right. I have three AC units and another capacitor went out this year and I found a kit with detailed instructions with pictures and phone support at hvacrepairkits.com. It saved me over $200 on the capacitor replacement.
There probably isn't a reset button=magic fix. With it in heat pump mode and tstat set above indoor temp, check your outdoor unit to see if it's operating. If not, check all breakers to it. Can you see any ice accumulated on the outdoor unit? If it is running and not producing heat, turn the tstat to emergency/auxiliary heat. and the heat pump turned off to prevent damage. You'll need a service tech.
Usually when the furnace blower motor runs all the time
The limit switch or rollout switch is usually open or bad.
The furnace board is seeing that one of those switches is open, so it brings the blower on to try to get the heat out of the combustion chamber area, so the switch will close. But if the switch is bad and won’t close, the furnace board will keep the blower running continuously.
The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.
Turn Tsat to fan to see if inside unit will come on. If it does Tstat needs replaced. If not it is fan motor or fan relay. Possible cap. Do you here the fan relay come in. If it is a Good man unit it is time delay and you wont here it. Need to know your make of unit. Rusty
