The hum you hear is the compressor running. The fan motor capacitor is most likely problem. The top of the capacitor should be flat. Bad ones will likely be puffed up. Other cause, bad motor.

Two things cause a unit to ice up restricted air flow over the evaporator coil (it's the one that ices up) Can be a dirty filter or the coil may be dirty or the return air vent may be blocked. Other cause is low freon.

2006 and later units have an X 13 GE non capacitor blower motor. Many many thousands have failed. There is a 5 year parts only warranty,if it has expired a new motor will cost $550.00 plus installation cost.

Replace the thermostat

The buzz is the compressor failing to start.The blue or purple wire from the compressor goes to herm on the capacitor. If it's wired right and does not stare the compressor is bad.

New fan motor should have a new capacitor (look on the motor for the mf number and use capacitor that size) .If changing the capacitor fixes it save the old motor, it's still good

2006 and later models have a X 13 blower motor. several million have failed. There is a 5 year parts warranty but you must pay for service to replace it. After the warranty expires a new one costs around $550.00 plus installation cost. Look on the end of the motor if it's an X13 there is no capacitor. If it's not an X13 the capacitor is the most likely problem.

At the existing capacitor: Connect one wire to herm one to common.When there are three connection points the one marked fan is not used for the hard start.

100 to 1 odds the capacitor got zapped when the power went off.Top of the capacitor where the wires connect should be flat. A lightening strike will cause it to be puffed up.

PUT hose and check other end

Check outdoor unit ,if the outdoor fan is spinning ,check if the compressor is coming on , if both fan and compresseor are working it may be low on refrigerant

The small wires that go from your furnace to the outside unit could be freyed or bare and touching something or maybe even together. Some time dogs will chew these wires outside or under a house if you have a crawl space. You may need to inspect the wires . If looks bad, you can go to a local hardware store and buy new wiring.

I have seen the contactor also blow this fuse. Especially if the contacted are pitted or at time the 24volt coil will be shorted.

These are the two main problems that could be occurring. Good luck. Mark

If your temp settings our high or low it will effect the blower, Look to see what your temp settings our and also check and see if you have a fresh air blower.

Either the coil pan is cracked, or the coils are not set properly. if coil pan is cracked, you have two options, Replace the coil, or get a condensate pump. The condesate pump is a temporary fix because some water would stay in the secondary pan and eventually rust it out, causing damage to whatever is below it, which is usually your ceiling.
