Hello , I have a Bryant furnace/ac that the indoor fan motor is changing speed from too slow to too fast . It is an ECM motor . When it is going too slow the suction line freezes up and then when it goes too fast it freezes up. The TXV was already changed and the filter dryer . What else could cause it to freeze up ? I recovered the charge and weighed it back in . I can only guess at this point it is an airflow issue. Any ideas?
