Problem Air conditioner kaput (Dometic 15K BTU A/C + Heat pump)

[Neal]

Can you wire it back to original without the soft start to see if it will run?

I didn't keep the original parts. I have another soft start on the way and I'll check the components tomorrow to see if there are more capacitors and get numbers off of them to order and make sure the fan motor spins freely which I believe it does.

Easier to just get a multimeter that will test microfarads and test the capacitor.

ITs really easy.

I had one go, years back. If you go up in the roof, take the cover off…and use the EasyTouch to turn the unit on. Carefully give the fan a spin by hand. If it runs with the hand prop… then the capacitor is almost certainly failed.

then the capacitor is almost certainly failed

Which capacitor? How many are there? Is this the soft start or some other?

I believe there are two, if I remember from the Newmar Academy correctly.

Let me see if I still have my notes and will post the numbers for them.

Here is what I put in my notes from the Academy class...

• No compressor – check start and run capacitors
  • Start – 50 to 55 micro-farads
  • Run – 15 to 20 micro-farads Fan
    • 25 to 30 micro-farads Compressor
