| Customer Reviews: Average Rating:  Rating : - Not for gas furnace use...poorly designed switch, no replacement parts available I have had three of these pumps fail just in about a year each. The failures were caused by the main float switch that turns the pump motor on. The switch contacts appeard burnt, probably because of arcing. My guess is that when used with a gas furnace, the condensate comes in so slowly that the switch sometimes barely makes contact when the tank is close to full, resulting in arcing and eventual failure.
When I tried last year to get a replacement switch, I was unable to do so. However, the Field Controls manual lists a main switch/float assembly, so I'll try Monday to get one. If the part is not available, the only option will be to replace the pump entirely.
The technical support last time was polite and did send me a new pump (which has since failed). They also tried to send switches, but the switches they sent were not the correct ones, so they were of no use to me. I don't blame their support (they did their best), but I do blame the company for poor design and especially for not having replacement parts available.
This is apparently a common design flaw problem for this type of pump: another company, Hartell, even has main switch replacement instructions on its web site (which implies that parts are available--YEA!).
If I can't get parts for this pump, I'll be buying a pump for which replacement parts are available. Little Giant pumps seem to get excellent reviews, as do Hartell pumps. The Little Giant pump specs say it has a "snap action" switch, which might avoid this problem. Its instruction sheet also has a complete parts list with part numbers. The Hartell pump has a three-year warranty, but one reviewer noted a failure just after the warranty expired. There are no part numbers listed in the instuction sheet, but the switch is listed on Hartell's web site. + See Full Customer Review |  |
