I have an older duo-therm & the compressor quit comeing on. SO, I thought I would replace the start capacitor and the run capasitor,well the little one came right out,but it looks like the red one has been installed at the factory & had a rolled/crimped edge where I can't get it out,QUESTION: can I just hang a replacement on the side?

Yes: Secure it well and you should be OK.
You don't want it coming off and shorting out. You can strap it anywhere
close by. Be sure all the wireing is
disconnected from the old cap and properly installed on the new one. Be sure the new cap. is rated the same.
GOOD LUCK

I have a duo-therm, one of 3 on the bus and one of them while running acts like the compressor does not want to start...the lights dim in the coach and it makes a sound the compressor does not want to come on. But it is cooling and I can tell the compressor does come on normal sometime. What could be the problem?
Happy Trail,
Brent

sounds like the same thing Brent, I'm definitely not an A/C person.BUT, this is what I've found out so far,the start capacitor gives the motor an extra boost',then the run capacitor kicks in, when the lights dim ,that means that one of them is going out & it can burn out the other one,the silly thing I did, I 'thought' I was changeing out the start/run capacitors & I was in the WRONG area., I changed the thermal overload on top of the dryer,just went in & talked to a Duo-therm guy & he sez the capacitors are under a metal cover ,I still haven't gottten up on the roof to find them

BRENT- Bob is correct in thinking that the start
capacitor is probably getting weak or has gone bad. A weak or bad cap. can eventually toast the
compressor and also the fan motors. I usually
change out both start and run caps at the same time even though only one is bad. That has been standard practice for me for many many years.
Caps are fairley cheap in comparison to the labor
it takes to replace one maybee next month. Your
compressor and fan motor will LOVE YOU for it
and maybe deside to stay around for a long time
Good Luck
