About 18 months ago I put soft starts on both air conditioners. Both worked absolutely flawlessly until about three weeks ago when the rear one failed. Only symptom was the compressor wouldn't run.
Contacted them and they said remove it and see if that fixed it. It did and since I registered online for the three year warranty I thought all was well. Problem was that I didn't buy them directly from SoftStartRV so I was told to file my warranty claim through the seller, they would send me a replacement, and SoftStartRV would replenish their stock.
Turns out the 3rd party seller I bought them from had gone out of business. I notified SoftStartRV and they went ahead and sent me a replacement.
In the future I'm going to bypass third party sellers and go straight to the source.
