Hello,
We have a 1996 Dutchmen pull behind RV. We were hooked up to 50 amp service while camping and our rooftop ducted dometic ac went out suddenly. Flipped thermostat to cool/ fan on and made a loud buzzing noise. Once home we replaced the two capacitors (I believe run and fan) which fixed the buzzing noise but fan will not run but compressor does.  Fan will also not start turning by hand. We cleaned the coils and removed all debris. We then replaced the fan motor in addition to new capacitors and still no fan but compressors runs. The room air blower fan and condensor blower fan (squirrel cage) both spin freely on new motor shaft. What else are we missing? Thank you so much!

Update: just want to update this incase anyone comes across this post googling for the same problem. The fan relay on the control board was burnt out. Happy camping!
