Fan Won't Start Unless I Spin It On RV AC

by John Kroska

Question: My AC compressor comes on but the fan won't start unless I give it a good spin manually. Do I need to replace fan motor? It's a 2002 Dometic Duo Therm.

Robbie: Yes you will need to replace the motor. When you order the motor be sure you order the complete kit as it will come with new fan blades. Many times replacing the motor requires you cut the shaft because the fan blade it frozen to the motor shaft and won't slide off.

Thanks for the Question Good Luck,

Fan wont start

If the fan wont start unless you spin it, and then the ac starts to work. My problem is I don't agree to replace the fan motor. To me it sounds like a bad capacitor. Was that checked? Or after installing the new fan motor , the capacitator was replaced also?
