Humidifiers and Dehumidifiers - Dehumidifier rewire switch?

I have a Kenmore dehumidifier, model 58054701400. We bought it in August of 04. It worked fine until the summer of 08, when it started freezing up. We took it in for service three separate times. We picked it up on 6/7/08 receipt reads: Service request: not collecting; Special instruction: TB=CC//; Tech Comments: Completed PM check (no IW), passed operational test. We took it home and it still didn't work, so took it back the next day. We picked it up again on 6/14/08 (can't find that receipt). I'm pretty sure we muddled along with it not working well until we finally took it back again on 8/8/08 the receipt read: Service request: recall. not collecting. full bucket light always on; Special instruction: TB=CC//; Tech comments: Found problem with blower. Dehum repaired. Passed operational test. We were able to use it for the remainder of the season, but had trouble again this summer. We took it in on 6/6/09. Repair ticket reads: Service request: Unit freezes up; Special instruction: TB=CC//Sent to PA Dept on 6/8; Tech Comments: Found problem with evaporator, repaired, passed operational test. We found that it worked, but only if we did not try to use the energy saver feature (3 or 6 hours on and off) and used only the humidistat setting (we set it to 50). Our service agreement had run out by this time so we didn't take it back. We have a hygrometer so we went through the rest of the summer turning the dehumidifier off whenever the humidity went below 65% and back on when it went above 70%. These cycles lasted anywhere from a day or two to most of a week depending on the weather. A week or two ago when I went to turn it back on, I got no response from the power button. What I want to know now is whether there is any economical way to use whatever capacity might remain in the refrigerant and blower functions without replacing the original electronics, which would no doubt be impractically expensive. I'm wondering if it would be possible to use a less expensive version of a humidistat and power switch, bypassing the original. Thanks for any help you can offer.
