Also:

I suggest you remove the oscillator coil and bake it in an oven for 30 minutes at 200 degrees. The heat from a heat gun could easily be too much for that coil. A controlled 200 degree heat will not harm the coil.

Set it on an old metal pan, covered in aluminum foil so the wax that will drip off goes onto the foil, not the pan.

Let it cool, make sure the windings are good, and reinstall.
