Thermostat CR36/49/50/65/100/120/DR130/DR85/BI135/(85/130 until 2008) – code: SEA00031DA – Isotherm

The Isotherm SEA00031DA thermostat It is a replacement dedicated to temperature regulation on a selection of Isotherm refrigeration units. It is designed for those who need to restore the correct functioning of temperature control on refrigerators and, where provided, on specific models of ice makers, maintaining the original system configuration.

In the nautical and onboard plant engineering field, an efficient thermostat is a key element for stable refrigeration management: when the component is worn or not working properly, abnormal behaviors may appear (imprecise regulation, inconsistent cycles, difficulty maintaining the setting). With this replacement, the goal is to return to temperature management compliant with the manufacturer's specifications, without unnecessary modifications or adaptations.

Spare part features and details

This product corresponds to the Isotherm SEA00031DA code and is offered as a replacement thermostat for various models in the Isotherm range. Its function is to manage the temperature regulation command according to the selected setting, contributing to the normal operating cycle of the unit.

Product identification

• Brand: Isotherm
• Spare part code: SEA00031DA
• Type: thermostat (temperature control spare part)

Indicated models (declared compatibility)

The thermostat is indicated for the following models:

• CR36 / CR49 / CR50 / CR65 / CR100 / CR120
• DR130 / DR85 / DR49
• BI135
• BI85 and BI130 (up to 2008)
• BI41 (up to 2010)
• Ice Maker White G112

Note: compatibility may depend on the unit version and year of production. In case of doubt, it is advisable to verify the spare part code on the installed component or in the equipment documentation.

Content and configuration

The product is supplied as replacement thermostat. No additional details on accessories or wiring are included: for this reason, during ordering it is useful to visually compare the existing component and refer to the manufacturer's instructions.

Typical applications (nautical and plant engineering)

The SEA00031DA thermostat is used as a spare part in maintenance and restoration interventions on Isotherm refrigeration systems installed in contexts where reliability and continuity of service are important, such as:

• Boats (onboard refrigerators and, where provided, compatible ice makers)
• Recreational vehicles and technical fittings (when compatible Isotherm units are present)
• Mobile applications where orderly temperature management of the unit is required

It is a component recommended when you want to keep the system in its original configuration, replacing only the control element without intervening on other parts of the system.

Operational advantages

Choosing a spare part identified by the code SEA00031DA helps simplify maintenance and reduce the risk of incompatibility compared to generic or non-matching solutions. In particular:

• Targeted replacement: designed for a specific list of Isotherm models, useful for replacement interventions consistent with the original.
• Temperature management: component dedicated to regulation, essential for the normal operation of the refrigeration unit.
• More straightforward maintenance: when the code matches, the intervention is generally simpler compared to adaptations.
• Suitable for technical contexts: typical spare part for installations in the nautical field and mobile applications, where scheduled maintenance is part of system management.

A correctly selected thermostat helps keep the unit in operating conditions consistent with the manufacturer's design, avoiding unnecessary interventions on other components.

Use, replacement, and important notes

Replacing a thermostat requires attention, especially in systems installed onboard or in confined technical spaces. For a correct and safe result:

• Code verification: check that the requested replacement is actually SEA00031DA and that the unit model is among those indicated.
• Comparison with the existing component: before installation, compare the new thermostat with the removed one (shape, connections, positioning) to avoid errors.
• Follow the manufacturer's instructions: adhere to Isotherm procedures for disassembly and reassembly, including any indications on positioning and fastening.
• Professional intervention: if you have no experience with refrigeration systems or onboard installations, it is advisable to rely on a qualified technician.

When to consider replacement

In general, thermostat replacement is considered when temperature control does not respond correctly to adjustments or when behaviors inconsistent with the selected setting are observed. Before proceeding, it is good practice to exclude other causes (wiring, connections, settings, general unit conditions) following the diagnostics provided by the manufacturer.

Note on “up to” models”

For models indicated with a year limit (BI85 and BI130 up to 2008, BI41 up to 2010), compatibility is linked to the specific version. If the unit is from a different period or if updates have been made over time, it is preferable to check the code of the installed thermostat or consult the technical documentation of the device.

For support in the choice, it is useful to have available exact model of the unit and component code currently installed: these elements allow you to quickly confirm the compatibility of the spare part.
