How To Test The Temperature Controller
This test consists of measuring the amount of resistance in the Temperature Controller. To do this, first, turn the autoclave off and unplug it from the wall
WARNING: CURRENT MUST NOT BE PRESENT WHEN MEASURING RESISTANCE.
Testing the Temperature Controller is a simple procedure.
- With the cabinet removed, look behind (on the inside) of the middle knob to find the controller
- Set your Volt Ohm Meter to 200k in the ohms section (indicated by the omega ω symbol)
- Place a probe on each of the two outside terminals (There are 3 terminals that stand off the controller as shown in the picture above) Reading should be 20k ohms
- Now place a probe on one of the outside terminals and one probe on the center terminal. Reading should be 10K.
- Rotate the knob counterclockwise as far as it will go. The meter should approach 0 on all configurations as above
If your readings are as above, the Temperature Controller is good. If they are outside of this range, the Temperature Controller is bad and needs to be replaced.
(See, we told you it was simple!)
