I purchased an Aprilaire Dehumidifier from Sylvane that came with a 5 year warranty. It was "bstock" that supposedly had only cosmetic damage. Their site states that such units are in perfect operating condition and come with the full manufacturers warranty, 5 years in this case. I was suspicious of it but Sylvane convinced me the unit was operating properly. After about 2 years it started icing up and shutting down. I found that an impact prior to my purchase had knocked the compressor out of line and must have caused a minor refrigerant leak. I contacted Aprilaire who were prepared to replace the unit, but when they checked their records they found Sylvane had already claimed the warranty on this unit so Aprilaire will not warranty it. Sylvane refuses to do anything.
