Capacitor for Coleman AC

[CHunley]

How do I check the capacitors on my coleman ac? I have them out and I have a digital multimeter, all I need to know is what I am looking for when tested???? Any help would be awesome

CHunley,

Checking capacitors is best done with a capacitor tester. But can be accomplished with an analog or dial type ohm meter.

The following information is from a Dometic Service Manual. It contains common information about testing capacitors.

Please use extreme caution when dealing with capacitors. They may still hold a charge!!!








Hope this helps.

See if the top is poped up if so it is bad or use the olm meter I have tested Caps this summer that look good but the read weak with a cap tester

IMO the only valid test of a capacitor for motor starting/running use is substitution. Too many variables for a simple low voltage test to be anything other than a very crude test for a complete failure.

Hey there all, just wanted to update the situation with the ac. The moderator gave a link, I printed the stuff out and went to the rv and followed the breakdown for troubleshooting. Led me to the thermostat, changed it (61.00) all is great. Thanks for the info.
