If I have to get on top of the coach, I can't do that. how else can I check the voltage? Share this post Link to post Share on other sites
dickandlois Report post Posted August 18, 2019 Think you need to find a mobile service tech or service center for your AC issue. The parts and testing them are built into the Roof AC units and that is where the repair(s) need to start. This is one of the best locator links I have found if they are unable to offer any help. They might be able to offer a possible service center contact number. https://fixonroad.com/home/ Rich. Share this post Link to post Share on other sites
kaypsmith Report post Posted August 18, 2019 I live close to Birmingham Alabama, I have a Carrier Air V that I pulled off the roof last spring, it is non ducted but only difference in the units is the inside cover contains controls, your controls will work with it. The fan assembly is broken and I was unable to find a replacement fan. The rest of the unit works and cools great. Free for the asking if you find someone that can make the change. I have not checked shipping price yet to Sunset Tx., but can or if there is someone coming close that can take it to you. This unit as I said works great, but the fan motor locks because of imbalance due to cracked fans. Share this post Link to post Share on other sites
eric@babin.com Report post Posted August 18, 2019 This probably won't work but now I do this for EVERY issue, because it does work about 1/4 of the time.... Unplug, shut down everything.... shut off chassis battery and coach battery banks..... wait 60 seconds and power back up.... I guess this resets / reboots everything and fixes things you never thought it might.... for our a/c when the thermostat freezes up, this is the only way to fix it.

RonaldNC Report post Posted August 19, 2019 I had a similar problem a couple of months ago. Everything looked good... but the compressor wouldn't come on. Per the service manual, I tested the start/run capacitor and it was bad. I bought a new one (hard to find) and now it starts/runs like a champ. Unfortunately, you'll need to get on the roof to check it. If you can't... call a service tech. If you need the service manual and parts manual, I would be happy to email it to you. Just send me your email address. Good luck, Ron Share this post Link to post Share on other sites
manholt Report post Posted August 19, 2019 Eric, if you freeze up, take it off Auto and use High cool. I'm currently doing that on both of my working AC's due to high humidity! My welcome back to USA from 2 months in Eastern Canada present !!! Share this post Link to post Share on other sites
f442485 Report post Posted August 19, 2019 I had the same issue. it was a dirty/loose connection at the start capacitor. Share this post Link to post Share on other sites

That is the problem... when I say the thermostat "freezes up" I don't mean cold freeze... I mean no buttons work... can't change it off anything... it's stuck!

manholt Report post Posted August 19, 2019 I have the same...I have had TCC look at it, that day it worked fine! 3 weeks later, stuck again...I hit it yesterday, so far, so good. I will be replacing my AC System later this year, so new Thermostat. Share this post Link to post Share on other sites

Thanks, Ron Ron, I'm not sure it's an exact match to what you need, but here is where I bought it in Ebay. https://www.ebay.com/itm/Trane-45-12-5Mfd-440V-Rnd-Run-Cap-OEM-CPT0688/381974411981?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20180105095853%26meid%3Dd100968a6f0e496385b8a2d0ef495102%26pid%3D100903%26rk%3D1%26rkt%3D8%26mehot%3Dlo%26sd%3D372557506355%26itm%3D381974411981%26pmt%3D0%26noa%3D1%26pg%3D2509164&_trksid=p2509164.c100903.m5276 It's a 440 volt, instead of 330 volt... but that's okay. It is physically larger than the original, but I found a spot above the fan to attach it. Just used some really strong two-sided padded tape to hold it there. The other option is to buy two separate capacitors (In my case a 45 Mfd and 12.5 Mfd) and do a little rewiring. I didn't like that option, but it would also work. If you need more help, just email me. Good luck, Ron Share this post Link to post Share on other sites
