Personally, I would keep the wafer thermostats. They're pretty easy to replace and not very expensive. Heating coil is an easy replacement also. But as long as it works, I'd leave it. If you think it may go out, then by a replacement to keep on hand. As for the fan motor, vacuum any dust and lint off of it and add a couple of drops of oil every week or so.
I put new wafers and microswitches in mine and it is rock steady.
I've been using the remote Incutherm thermometer/hygrometers for a few years and got tired of them never being accurate. I bought an old style dry-wet bulb thermometer to hang in the window of the door and now I rely on that more than the Incutherms.
