Autoclave Repair Tips

Having heat problems with your  Tuttnauer 2540M Autoclave?   Wondering if it could be the heating elements?  Now you can know for sure

How To Test The Tuttnauer 2540M Heater Element

This test consists of measuring the amount of resistance in the Tuttnauer 2540M Heating Element. To do this, first, turn the Tuttnauer autoclave off and unplug it from the wall

WARNING: CURRENT MUST NOT BE PRESENT WHEN MEASURING RESISTANCE.

Remove the cabinet from the Tuttnauer 2540M to give you access to the heating elements.  Then test each one.  Do not stop after you have found a defective element, test each one.

Set your volt/ohm meter on 200 ohms (200 NOT 200k). The ohms range is located within the Omega ( O )(look for this symbol) section of your meter. It is also the area with “k” ranges (ie: 2000k,. 200k, 20K and then 2000, 200).

Disconnect the wires from each heating element before testing to keep from getting a false reading. 

Place a probe from the volt/ohm meter on each terminal of the 2 terminals on the Tuttnauer 2540M element (it really doesn’t matter which color probe goes where).

For the Tuttnauer 2540M 120v model, heating element to be good, it must  measure  between 36.9 and 45.1 ohms .   If your reading is outside of this range, then it is defective and needs to be replaced.

Replacing the Heating Elements on the Tuttnauer 2540M is not difficult and does not require any special tools.  And it is something you can do.

If you are experiencing heating problems with you NAPCO 704-9000 Autoclave, the most likely cause is the Heating Element.  No need to call the service company.  You can easily test it, and yes, even fix it yourself

There are 2 different heating elements used on the NAPCO 704-9000 and you will need to dtermine which one you have.  One is rated at 150 watts while the other is rated at 1400 watts

You will need a volt/ohm meter to perform this test.  It doesn’t have to be anything fancy.  A cheap one will work just fine.  The easiest one to use is one with a digital readout.  (These sell for less than $20.00 at places like Wal-Mart, Home Depot, etc)

This test consists of measuring the amount of resistance in the Heating Element. To do this, first, turn the NAPCO 704-9000 Autoclave off and unplug it from the wall

WARNING: CURRENT MUST NOT BE PRESENT WHEN MEASURING RESISTANCE.

Set your volt/ohm meter on 200 ohms (200 NOT 200k). The ohms range is located within the Omega (Ω )(look for this symbol) section of your meter. It is also the area with “k” ranges (ie: 2000k,. 200k, 20K and then 2000, 200).

Place a probe from the volt/ohm meter on each terminal where the wire connects to the NAPCO 704-9000 Autoclave Heating Element (it really doesn’t matter which color probe goes where). 

Now look at your readout.  A good NAPCO 704-9000 Autoclave Heating Element will have a resistance range of between 10.37 and 12.67 ohms for the 1250 watts Heating Element & between 9.26 and 11.30 ohms for the 1400 watts heating element
