Thermo Electric Modules

Forum, Centrifuge is showing "502" on the diagnostic display. Traced the problem down to the thermo electric module board under the bowl. One of the modules is open. Does anyone have specs for these modules? (wattage, amp draw, voltage) The print on the module reads: Melcor 5729. The board from Beckman is very pricey. Is there a source for replacement modules? The only thing I have to go on is the physical dimensions. A stack of papers sucked up against the cooling fan intake, in our case, may have caused the module to burn out. Lance
