If you don't have something in the house that uses water constantly drawing on it, then it strongly implies a rupture in your expansion tank bladder - get that tank replaced pronto - I'm not kidding, don't wait! Replacing the tank may run you $250. Replacing a burned-out well pump is WAY more than that!
Because the pressure tank is "waterlogged" . This means the necessary air has evacuated from the pressure tank and it is now full of water. It should have about 28 psi of air in it. You will need to re-pressurise it.
This tank where the water enters from the pump is a critical part of your system . It should have an 'air charge' of approximately 27-28 psi if the pressure switch is a standard 30/50 switch. If this air charge has gone down, then your water pressure will be lower. If this tank is very old, possibly silver or green in color, then it's a "galvanised tank" and is possibly 'waterlogged'. This means you have to recharge the air with a compressor (just like blowing up an auto tire) To do this, switch off the pump. Open a faucet near the tank and let most of the water out. When you think it's nearly empty, close the valve to house and pump in with the compressor till the needle on your tank gauge points to 27, 28 psi. Now switch on the pump and the pressure should be improved. -IF your tank is a pale blue one, then chances are it's a 'bladder' tank and low pressure means your bladder is leaking. -You can pump it just as I said already, but in this case it will only last 2-3 months. You basically need a new tank.
In all cases check the size of the pressure switch. It's printed somewhere on it . 30/50 as I've mentioned is common but some are 40/60. In this case pump in 38 psi of air. Both pressure switches are adjustable to a small degree by turning the central spring up or down. It's essential that lower limit of this switch is 2-3 psi above residual air pressure.
Always use a good round tire pressure gauge, (available in auto stores for about $5.) to check tank air pressure, Don't rely on the installed gauge, they soon get erratic.

I do not know your situation but a good guess is that your well pump is always on and is not getting enough pressure to shut off the pressure switch. So I would shut off the power to your well pump and see if the buzzing stops and if it does then I would replace your well pump. If the buzzing don't stop with pump shut off then it could still be your well pump check valve slowly leaking threw but I think its your pump because its not pumping enough to shut off with or with out a bad check valve.
You can buy a timed switch mounted on the submersible pump. If you want to buy a submersible pump, you can choose VIDO's submersible pump, VIDO's submersible pump is of high quality and is the choice of most people.
Most well water must use a pump. Simply switch the pump off.
Depends on type of pump.
Relay is stuck.
yes
No. When a fuse blows it stops power from getting to the attached devices. It would power off and stay off. IF the fuel pump was attached to a self-resetting circuit breaker, then the power might cycle on and off.
The hot water is probably water running through the pump and recirculating in the sump. Is the pump running continually? Water that isn't ejected by the pump and is recirculated is being heated by the pump through friction and the motor heat energy thereby becoming hot. Find out why the pump isn't shutting off or the reason the water isn't being ejected out the pipe.
yes
Try disconnecting the battery. After a few minutes re-connect. It may reset computer. Turn light off.
First, is the thermostat in he correct position for cooling? Is there a red light glowing on the thermostat? There could have been a power surge or outage and the heat pump needs to reset. Turn the power off to the heat pump at the control panel for a couple or minutes then back on again to reset the heat pump.
