Yes, they do run hot enough to burn you. The fan should be running if it is that hot. Also should be placed in a ventilated area that can get plenty of free air and exhaust it. My Magnatek, which I only use as standby in the event of a failure w/my Trace inverter, runs hot enough to keep the fan going almost continuously. The product of energy conversion is heat!
Trace the fan motor wires to locate the activation switch. You'll most likely find it at the rear center of the lower part of the converter unit, near the step-down transformer coil. Disconnect all power sources to the rig, put a jumper wire across this temperature sensitive switch, restore power, and see if the fan runs when the converter is active. The switch is a click-on design, meaning it contains a bimetal disc that "oil cans" in reaction to heat and snaps concave to convex,or vice-versa, opening or closing a set of internal points. They are available in a wide range of temperatures, your switch should have a temperature rating marked on it. You can pick one up at an electronics store, or at a home appliance parts and repair---they can order the rating you need---.
Hello Again. Thanks for your great answers in the past.I LOVE this site!! I have another "rookie" question. My power Converter on my '93, 27' class C Gulfstream seems to run hot when plugged into AC. If I touch the big transformer looking unit I could burn myself. Is this normal. I'm affraid of a fire. Also should the fan always run or does it turn on when it gets hot. Mine feels hot but the fan is not going around. Thanks Again
HI...Snould the large black transformer get so hot that you could burn yourself on it before the fan turns on, or should the fan kick in when it is warm and not yet really hot? I really don't want to burn up my coach!! |
