Control Module Therm CA

The control module for Therm CA is responsible for controlling machine operation and the proper functioning of the control system in Kränzle pressure washers. This part is used during service repairs related to electronic failure or problems with the machine’s operating logic.

MPN / reference: 44952

Note: the module is available in versions for:

• Therm CA 11/130 - 230V
• Therm CA 12/150 - 400V

Before purchase, ask about the available version and confirm compatibility with your machine.

APPLICATION

The module is used in typical service work related to the washer’s electronics:

• replacement of a damaged control module in Therm CA machines,
• repair of the control system after an electronics failure,
• restoring proper machine operation after startup or control problems,
• servicing washers working in workshop, industrial, and technical environments.

SYMPTOMS - WHEN IT IS WORTH REPLACING

It is worth considering replacement of the module when the following appear:

• no proper machine response to startup,
• unstable control operation despite functional actuating components,
• recurring control system operating faults,
• visible signs of electronic damage during service inspection,
• failure confirmed by electrical diagnostics of the machine.

HOW TO CHOOSE THE RIGHT PART

Selection of the control module should be unambiguous:

• confirm whether the machine is Therm CA 11/130 (230V) or Therm CA 12/150 (400V),
• verify the manufacturer number: MPN 44952,
• compare the module markings with the removed part,
• check compatibility of the voltage and model variant with the service documentation.

With control electronics, the part should not be selected solely by appearance - compatibility of the voltage version is critical.

COMPATIBILITY

The module should be selected based on MPN 44952 and compatibility with the appropriate machine variant:

• Therm CA 11/130 - 230V
  Therm CA 12/150 - 400V

Before ordering, confirm which version is required and whether it is currently available. Selection without verifying voltage and model may result in incompatibility.

[faq]

Does this module fit both the 230V and 400V versions at the same time?|The product is associated with different Therm CA variants, so before purchase you need to confirm the correct machine version and availability of the appropriate module.

How do I check whether I need the 11/130 or 12/150 version?|The safest way is based on the machine rating plate, technical documentation, and the markings on the old module. The supply voltage is also crucial: 230V or 400V.

Does a startup problem always mean a damaged control module?|No. Similar symptoms may also be caused by other electrical system components, such as the power supply, protections, contactors, or wiring. The module is worth replacing only after the fault has been confirmed during diagnostics.

Why does the description say I need to ask about the available version?|Because the part applies to more than one machine variant and supply voltage. Without confirming the version, it is easy to order a module that is incompatible with a specific washer.

What should be checked after installing a new module?|After replacement, verify the correctness of the connections, the machine’s response to startup, and the stability of the functions controlled by the module. It is also worth making sure there are no other electrical faults in the system.
