When your Midmark M9 or M11 Autoclave Displays Error “Code C983 Heat Up Mode High Limit Thermostat,” it is telling
you that one or both of the high limit thermostats is in an “Open” State.
What this means is there is a High Limit Thermostat on your autoclave that is failing and blocking power from going on to the
other components of the autoclave. This is what is triggering the Error Code C983.
What you need to understand is, the PC Board directs all power to the other components (except the fan) in your Midmark
autoclave….through the High Limit Thermostats (there are 2 in your Midmark Autoclave if you are getting this error code).
And since the power cannot go any further, your Midmark autoclave is basically dead until you fix it.
While this type of autoclave repair may conjure up images of special skills, special equipment and tools, etc. the truth is…..it is a fairly
simple and inexpensive procedure (Note: It is only inexpensive if you make the repair yourself!) And no special tools or skills are required
