Hello! We are so excited about the purchase of our first RV - a 2008 Winnebago Journey 39z! We have had it for a few weeks now and love it but unfortunately the AC completely stopped working yesterday. Literally won’t even blow air through the vents. No warm air, no cool air, no air at all. Just nothing. Anyone else ever experience this?! If so, please help!

What electrical source are you using? Genny or shore power? Have you checked the circuit breaker for the AC? How are your coach batteries? Fully charged?

Right now generator. Yes we checked circuit breaker and batteries and everything looks A-okay! We are wondering it it’s maybe the fan or compressor?

Did you check the circuit breakers on the generator itself? If they are okay, then you will need to start checking for power flow through the transfer switch. Do you have a voltmeter?

Ac powers up and is running. The blower to the coach is not blowing. I think it could be the capacitor to the blower or the blower motor itself.

I assume you are talking about the house A/C, not the chassis A/C.

There are different A/C configurations in different Winnie RV’s. A quick search did not turn up how the Winnie 2008 Journey 39Z is configured.

An energy management system could have turned the A/C “off” due to high power demand. Switch the electric water heater “off”, electric refrigerator to gas or “off”. Switch any other high power 120 volt devices “off”. If the unit has more than one A/C, switch one of them “off”. See if the remaining A/C now works.

Most Winnie A/C require 12 volts for controls and 120 volts to power the fans and compressors. In addition to the 120 volt circuit breakers, look for blown 12 volt fuses.

Switching circuit breakers “off” and then back on is the best way to insure a breaker did not trip. Some are hard to see if they are tripped. Of course loose or corroded 120 volt or 12 volt wiring could be the problem.

I would measure voltages before throwing parts at the issue.

Measure voltage on the output of the branch circuit breaker for the A/C. It should be about 120 volts.

Measure voltage on climate control to verify 12 volts.

Check for 120 volt at the A/C.

Check for 12 volts at the controls connection of the A/C.

ClantonClan-

Welcome to iRV2!

Your coach is equipped with a "basement" A/C unit. There are a lot of threads on that topic on iRV2. Here is one:

Saga of the Coleman-Mach Basement A/C

If you end up having to service the unit, you'll want to read through "Duner's" removal procedure guide:

Basement A-C Removal Procedure-Revised 8-24-2013.pdf

He also has posted a Service guide:

Coleman AC Service Manual Newer Download.pdf

I hope these links help.

A couple of other things.

1) You'd probably get more/better responses if you had the moderators move this thread to the Winnebago forum. You can ask them to do that by clicking on the exclamation-point-in-a-white-triangle icon to the left.

2) You should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are here.

Okay so we are doing everything you all suggested. Right now we are getting the “ID or OD freeze temp out of range” “Morse Code” signal from the blinking green lights. Testing the voltage now….

ClantonClan · 08-07-2022, 03:34 PM

Also the fan motor is getting HOT just doing these tests. I can start posting pics but I don’t know how quite yet. New here. And BTW, thank you for all of your help!

ClantonClan · 08-07-2022, 03:38 PM

Voltage test failed.

Wanted to thank everyone so much for your help. We really appreciate you taking time out of your day for us! Just wanted to send out one final update.

We ended up ordering a $9.00 capacitor off of Amazon and switched it out today and it seems to have solved the problem. At least for now. We understand that the issue put a lot of stress on the fan motor and that may go out on us soon now as well but fingered crossed it doesn’t!
