GlennWest Posted November 20, 2016 Report Posted November 20, 2016 We replaced our main ac/hp dometic roughly 2 years ago. It will now come on but as soon as compressor kicks in, Breaker throws. Will go on roof today and clean it and check for what? Any suggestions for me. I do have an ohm meter. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
Jimalberta Posted November 20, 2016 Report Posted November 20, 2016 Check for loose wires. Check the capacitor for any signs of failing such as swollen, weeping , etc. Also check to see if your AC has a start capacitor....if it doesnt you should add one. If all looks good up there it could also be a faulty compressor. The fact that your breaker is tripping could be a fault in the AC or it could be a fault in with the breaker as well, you should check the breaker for loose wire or discoloring from heat. <p>....JIM and LINDA......2001 American Eagle 40 '.towing a GMC Sierra 1500 4X4 with RZR in the rear. 1999 JEEP Cherokee that we tow as well.

I'mdonewiththis forum Posted November 20, 2016 Report Posted November 20, 2016 Glen, first thing is Safety FIRST! I am sure you know that, but make sure there is no power to the AC unit. Then check the terminals on the compressor to the case. Any continuity is a shorted compressor. Check the wiring to the compressor for any chafing, wearing, burnt spots, etc. It is also possible the blower motor is the problem. It could be drawing heavy and when the compressor tries to start then it overloads the breaker.
D&J Posted November 20, 2016 Report Posted November 20, 2016 If it trips as soon as it comes on cleaning won't help, with the power off remover the cover on the compressor so you can see the wires, take your ohm meter and put on lead to a bare copper line and the other to each terminal. If you get continuity remove all 3 wires and check the terminals agian, if you still continuity then look for a new unit because the compressor is grounded. This is the first check, if the compressor isn't grounded then start checking the start and run caps.

GlennWest Posted November 20, 2016 Author Report Posted November 20, 2016 Thanks for the tips. Ya'll are great. As this unit is fairly new, I will not replace if compressor shot. Been wanting to change out to Mini spilts anyway. Will let you you know what i find. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
GlennWest Posted November 20, 2016 Author Report Posted November 20, 2016 ok, I pulled cover and fan was tight. Spun it and freed up. Huh!!! Turned on power and no air coming out vents. Guess I was wrong about compressor kicking in. Went back up, unit buzzing and fan locked. Could not turn it. Sounds like fan motor to me. No grease fittings. I saw no capacitor. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
I'mdonewiththis forum Posted November 20, 2016 Report Posted November 20, 2016 Well, congrats in finding the problem! Now get the mini splits ordered!
Rif Posted November 20, 2016 Report Posted November 20, 2016 There has to be a capacitor and what you are describing is a perfect example of a failed one. Get the manual for your unit and locate the capacitor. Replace it with a Supco SPP6 that you can find on Amazon for under $10. 2000 Volvo 770, 500HP/1650FP Cummins N14 and 10 Speed Autoshift 3.58 Rear 202" WB, 2002 Teton Aspen Royal 43 Foot, Burgman 650 Scooter
GlennWest Posted November 20, 2016 Author Report Posted November 20, 2016 Found it. In a metal box. Duh. It's a C65V (60+5) uF (+ with underline) 5% 370VAC 50/60 HZ P2 10000 AFC. Also made in China. lol. Also it has several wires, not just two as in unit you posted 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
D&J Posted November 20, 2016 Report Posted November 20, 2016 The 5mf side of the cap is for the fan motor, if the fan motor will not spin freely it will not start. The cap is for both the compressor and fan. Try getting some oil on both ends of the shaft and try and work it into tbe bearing.

GlennWest Posted November 20, 2016 Author Report Posted November 20, 2016 ok, i lubed shaft good. Turned very freely. had wife to turn on breaker and fan never moved and was locked solid. Turned off breaker and shaft motor turned then. Little stiff and freed right up. It warm too. Capacitor didn't buzz then. Had been one for a while when first checked and it was buzzing then. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
D&J Posted November 20, 2016 Report Posted November 20, 2016 If the motor will not turn with power to it with a little help from your hand then the bearings are bad and the rotor is pulled up against the stator.

GlennWest Posted November 21, 2016 Author Report Posted November 21, 2016 Going to West RV Service in Livingston tomorrow. Maybe they will have one. Not any luck finding one on line. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
Al F Posted November 21, 2016 Report Posted November 21, 2016 If you are looking for the fan motor, take the number from the fan motor and search on the internet. I had a bad fan motor and found the motor at Amazon.com. Cheaper than the local appliance parts store. The shaft in the motor would bind up. I would lub it and it would work for a day or so and then quit again. Al & Sharon 2006 Winnebago Journey 36G 2020 Chevy Colorado Toad San Antonio, TX http://downtheroadaroundthebend.blogspot.com/
GlennWest Posted November 21, 2016 Author Report Posted November 21, 2016 I looked for hours today. Either voltage wrong or not 3 speed. update Dyers has it. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
Jimalberta Posted November 22, 2016 Report Posted November 22, 2016 The 3 speed part is not really that important as ACs should run on high anyways to get the most out of them and keep the evap from freezing up. If the hi speed rpm and capacitor requirements matches your old one it would work with a wiring adjustment. <p>....JIM and LINDA......2001 American Eagle 40 '.towing a GMC Sierra 1500 4X4 with RZR in the rear. 1999 JEEP Cherokee that we tow as well.

GlennWest Posted November 22, 2016 Author Report Posted November 22, 2016 Should have one tomorrow or Wednesday at least. Went to Channelview RV today and ordered it. My unit is a heat pump also. Need the slow speed. Also met Phil aka Big5ther. We had a good time together. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
Yarome Posted November 22, 2016 Report Posted November 22, 2016 Replace it with a Supco SPP6 As long as you're going to keep using what you've got.. I would agree with Rif. For $10-$11 it's a VERY worthwhile upgrade to your C65V.

For $10-$11 it's a VERY worthwhile upgrade to your C65V. But my capacitor is duall 60/5. 60 for condenser and 5 for fan. Don't see where that unit would work. Anyway I don't intend to keep using it. Timing not right for mini split upgrade just yet. Need serious time off for this. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
Yarome Posted November 22, 2016 Report Posted November 22, 2016 Don't see where that unit would work. Anyway I don't intend to keep using it. With a dual cap you would install the SPP6 in parallel with your current start cap rather than as a replacement. (Just information for others since you don't plan on keeping it for long.)
GlennWest Posted November 23, 2016 Author Report Posted November 23, 2016 Got new motor today. Installed. Works fine now. Bad thing is though, unit less than 2 years old. Don't know if this is norm on new Dometics or not. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1
