Do you have any suggestions for cleaning product. Gunk is really caked on and in the coil.

Thanks for the prompt reply, while I'm on the A/C subject, the unit has two Dometic duotherm 13500 roof units. I am told that by removing 4 bolts and unplugging the wiring I can lift the units off and bring them down for cleaning and all I would have to do is replace the square foam gasket when reinstalled. Is this correct?

I am new to this forum. I have a vacuum leak in lines going to a vacuum solenoid near the vacuum pump. Does anyone have a vacuum line schematic for this motorhome?

I'm new to FMCA and happened to run across this forum. With three six volt batteries there is one pair of 6 volt batteries in parallel which ( for sake of argument) doubles the amperage and maintains 6 volts. This 6V pair is placed in series with the remaining 6 volt battery and as such the group of 3 batteries becomes a 12 volt power source. Think of it as one (now) large six volt battery placed in series with a smaller 6 volt battery.
