Can New Evaporator Fan Motor create an odor?

Our evaporator fan motor stopped working and we couldn't afford to put the variable speed fan motor replacement. Our ac person put in a universal fan motor that ran continuously and made the house very humid. We had him come back out after a few days and he put in a kit that enabled him to adjust the speed to medium high, and the humidity in the house is good, running around 42 percent. Since the new motor was put in, we have been having a strange smell in the house, mainly in one big room closest to the garage where the air handler is up in the attic. What is strange is that the odor is strongest by the return. We have an expensive filtrate filter in there that is suppose to trap a lot of different things including mold, etc. The smell is not musty like mildrew, but more like a mechanical/wiring smell. It is causing us to have allergy symptoms like burning eyes, sneezing, etc. It was recommended that I have someone come in and do a air test in our home, which is quite expensive but may be come necessary if we can't figure out what it going on. I'm not sure if by putting in a universal motor, maybe there is something going on with the wiring since we have a heat pump also. Any suggestions or input would greatly be appreciated. Thanks

First, its more likely that the thermistor was bad in your VS blower module. A very inexpensive repair. Much less then a new PSC motor.

If its wired wrong, your aux heat may be coming on and giving you that smell. call that company back out.
