We’ve had our 2008 Tiffin Phaeton since 2011. The middle 15K AC unit was diagnosed with a bad coil and compressor. It has been sitting in the shop for 2 months trying to get repaired. Needless to say, there goes summer and no camping.
We have discussed everything from replacing the unit entirely or repairing it. It is a Dometic unit, I believe. This particular unit is not on the market anymore and it’s replacement is a little different from what I’m being told. My repair guy said it was a bad coil and it took several weeks to obtain one. Now that it’s been fixed, he noticed that the compressor unit is also bad. The rotary compressor, Tecumseh model # 2490-879 is not an easy part to locate for purchase or a crossed-reference replacement. We’ve wasted a lot of time trying to repair the AC from above the roof, verses replacing the AC unit and ripping into the interior roofline, which is what we wanted to avoid. I’ve looked high and low on the internet for this part and I only have 1 potential lead which will probably fall through.
I find it very maddening that these type of EOM parts are not more readily available on the market. It would make repairing much quicker than a full replacement. Though I understand replacing the entire unit would provide longevity.
Right now, we are without a compressor and our vacation will be here in 6 weeks, so we’ll make due on 2 AC unit’s as it will not be so hot by then, hopefully. Afterwards, if we still have not found the compressor, our only hope it to replace the whole unit. And if you’re going to do that, you might as well replace all the old units at the same time.
We would love to trade this in for something newer, but will probably go in the hole, even tho we bought this RV $20K under blue book back in 2011.
If anyone can help us locate this compressor, we would greatful!
