Its probably a bad pressure switch where the contacts did not open when the exhaust fan shut off. Check the pressure switch ports and verify there not blocked.

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.

The filter slides out of the bottom of front grill. If there is no room to slide it down and out, remove the 2 screws (1 on each side) then remove front grill to access filter.

Problem could be a short in the wiring, bad thermostat, or issues with the fan control board.

Check for a frozen cooling coil. Turn the fan to the on position at the thermostat and the cooling to off. Your cooling coil may be iced over. Allow it to run in the fan only mode until the coil has had a chance to defrost. At the outside unit you may see the large line is frosted. This is the visual indication for a frozen coil. When you return the A/C to cooling use it with the fan on while in the cooling mode.

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
