Scheduled to arrive between 8:00am and 12:00pm on Monday, Refrigerator Repair Guy #4 appeared shortly after 1:00pm. At least he hit Monday. He glanced at the pile of parts sent here by previous repair guys, then pulled open the freezer. When the light didn't come on, he commented that he'd see if he had a new bulb in his truck. I told him not to bother - the lamp is fine; it just doesn't come on when the compressor is actually cooling because something in the switch freezes in the "off" position. I told him (as I've told all the other guys) that the freezer light coming on is the first sign of a defrost. He fiddled with the switch a bit, then disconnected it and disappeared to his truck, returning a while later with a new switch. He installed the new switch, explaining that the REAL problem we've been having is with the light. The switch had malfunctioned, keeping the light on even when the door was closed. The heat from the light was causing the compressor to overwork and eventually shut down to save itsself from burning out. Ummmm....sure. I must have looked pretty scary in my sincere effort not to say something I would regret in court, because he stopped talking about his light theory rather abruptly and turned his attention to the 36 pound pile of parts stacked up beside the fridge (28 lb compressor kit, two freezer drawer rails, 4 lb each). After a moment of consideration, he determined that he would go ahead and replace my compressor anyhow. And that he'd go ahead and install the new freezer drawer rails, too. Because they were here. And, possibly, because he realized that he might be twice my height and three times my weight but I would take him down if he didn't. Smart man. He spent the better part of three hours working on the fridge and I'm pleased to say that our fridge hasn't ever operated as quietly as it does now and, as a bonus, it's been keeping things cold for over 30 hours in a row! It hasn't done that since June! Chris bought ice cream today to celebrate and I'm off to get started on eating it...just in case.
