Has the freeze up problem gone away?? I hope its coincidence, but it could be that during the condenser fan mtr change out, U may have started a freon leak. U may have disturbed a bad weld joint or possibly one of the screws U removed to take the top of the condenser off has now punctured the coil when U re-installed it. Some quick checks:
I'm ass-uming U have run the unit after the mtr change out. Shut the power off 2 the condenser section and remove the top again carefully. Check all around the condenser looking 4 any oily/dirt spots. Pay particular attention to the areas where the screws go back in. U can make a bubble detector solution by mixing dish washing detergent with water. Use more detergent then water to make it so its not to runny. Use a paint brush and paint any suspect areas.
Even if U don't C any oily areas paint the pipe connections to the compressor-any screw areas that are close to the coil-where the pipes exit the condenser. It may not be a big leak that makes a lot of bubbles. It could be a squeaker and U might just C a little foaming. B patient.
If U have a set of service thermometers, stick 1 in the return air to the evaporator section (the furance section) & 1 in the supply air (cold air to the house). Do it as close to the cooling coil as U can. Your looking 4 a 18-22 degree spread between air in and air out. Example: return air is 74 degrees and supply air is 54 degress= 20 degree spread. If the sprerad is low (<=14 degress) U may B low on charge.
