Shut off the electric to your furnace.

the reason that the line is frozen is because of one two things:
First there is enough air passing over the A coil on your furnace.
Could be dirty filters - closed vents- furnace fan will not run/ stops and starts (bad motor).
Second the charge on your a/c unit is low.

This is likely caused by a faulty blower motor bearings, or the fan has something in it or it could possibly have broken. Shut down power to unit, remove cover and inspect the fan shaft, blades, and spin it. it should freely spin. If it hangs up you likely have a bad blower motor.

Man, it sounds like you have a heat pump with a bad defrost board or reversing valve. I assume your description of the unit outside freezing up is the condenser and the blower you refer to is the condenser fan motor. Or, is it the big copper line to the compressor that is freezing up? If so, have someone stand by the inside blower and listen for a click as you move the thermostat fan switch from auto to on a couple of times., Make sure at the time you are testing that the thermostat is in the off position. Those 2 switches operate separately. If you hear those clicks during the test you probably have a bad blower motor if there are are no clicks you may have a bad blower relay or board. Hope this helps good luck.

Your fan motor might be on the way out, and causing the motor's internal overload to trip.Try feeling the fan motor with the palm of your hand after it trips out.If it's hot (without using test instruments), then I'm willing to bet that fan motor is defective. If it has a variable speed ECM motor, it could just be the electronic module on the back end. some manufacturers will allow you to buy the module separately.If it's an ECM, contact me after you get an ohmmeter and I'll walk you through it. I have a simple inexpensive fix

Hello, the drain line will be located under the unit near the condenser coil. Sometimes it can get blocked and the condensate will settle toward the front of the unit and leak from the unit. Also, make sure the unit is tilted back in the window about a 1/4 inch aswell.
