Customer Question

Re Trane TRA4TWX5036A1000A 3 ton heat pump. Sometimes the outdoor fan makes a pulsing noise as if it tries to change speeds then doesn't. It has this problem both in heating and cooling. It does not do it every time the unit operates but when it does do it the problem exists for the whole operating cycle
