Problem: Power-On Light does not illuminate

Possible Causes & Solutions

The first thing you will want to check is to make sure the autoclave is actually plugged in. I know it is obvious, but you would be amazed at how many times that turns out to be the problem

Next, check to make sure there is power coming to the outlet where you have the autoclave plugged in. Check your circuit breaker and make sure it hasn’t tripped.

If you have a GFI outlet, try resetting it and check for power. GFI outlets, especially ones that simply plug into a wall-outlet do go bad frequently.
Test the power cord coming from the outlet to the back of the unit for continuity. You will need to flex the cord while testing it to make sure there aren’t any breaks inside.

If it is not continuous, the cord has a break somewhere inside and will need to be replaced.

Next, if your Tuttnauer Autoclave is equipped with a Circuit Breaker, try resetting it. If that doesn’t remedy the problem, test it for a short and replace if necessary.

Now, you will need to test the Power Switch. The Power Switch simply breaks the power and keeps it from going any further when it is turned off, and allows the power to continue through it when it is turned on

To test the power switch, you simply test it for continuity. It should be continuous when turned on, and not continuous when turned off
Now you will want to check the wiring for an open circuit. Check for loose, disconnected, broken or burnt wires. Replace wire harness if necessary.

Maybe, this should have been first, instead of last…..but now test the power light itself. It could be the light has simply burned out and needs to be replaced.
