If I need to put in a new thermostat do I need to take the fan assembly out? Can't see how it would be doable otherwise. I've read about a'microswitch" but can't figure out what or where it is. THANKS FOR ANY HELP!!
The microswitch is located under the wafer and looks like this:
The small silver button on the top is what the wafer contacts when it expands. It pushes down and opens the electrical circuit turning off the heating element.
It is held in place by 2 small diameter bolts and nuts that go thru the to hole you see near the bottom.
The wires are connected by screws on the bottom.
When I replaced mine, I took out the entire frame that holds the wafer and the switch. You can test the switch first by pressing on the button. You should hear a click. That tells if the button is actually depressing. If it's not, you can try some wd40 and a q-tip to clean it up. If it's actually clicking, you can test the circuitry with an electrical multimeter to tell if the internal circuitry is working correctly.
Is this an incubator that you have had for a while and has worked for you or is this a new one for you? I ask because I purchased a #416 a few weeks ago and someone had wired the thermostats incorrectly and even though I had put in new wafers and switches they would not work correctly.
Message me if I can help you any with it.
