Loading…Electric coil
At Hewa you will find electrical coils for ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps. This category is intended for installers, service technicians and technical buyers looking for a suitable coil for actuation, fault diagnosis, maintenance or replacement.
An electrical coil is used to electromagnetically actuate a valve, expansion valve or control component. Always check the exact heat pump model, article number, EAN, voltage, cable length, plug type, connection and technical application of the original coil before ordering.

Electrical coils for ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps
Electrical coils are used in compatible ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps to control electrical or electromagnetic components. A coil can be part of a valve, relay function or control component and is often driven by the PCB or a related control circuit.
For service, diagnosis or replacement, the electrical coil must match the exact technical configuration of the unit. The correct spare part depends on the series, unit type, article number, voltage, power rating, connector, cable length, coil resistance, mounting position and the component on which the coil is installed.
Important checks for an electrical coil
- Check whether the electrical coil is suitable for the relevant ALPS EXCLUSIVE ARTIC or URBAN LINE version.
- Compare the article number, supply voltage, plug connection, cable length, coil type and mounting form with the original component.
- Inspect the coil for overheating, discoloration, damage, moisture ingress, cable breakage or a burnt smell.
- Measure the coil resistance where required and check whether the control signal from the PCB is present correctly.
- Also check the controlled component, connectors, fuses, wiring and the technical condition of the related circuit.
Application, replacement and technical attention points
An electrical coil may need to be replaced when the controlled component no longer switches, the coil no longer produces a magnetic effect, fault codes appear or an electrical interruption, short circuit or thermal damage is detected. A fault may sometimes appear to be caused by the PCB, while the actual cause is the coil, cable or connector.
Work on electrical control components must be carried out by a qualified technician. After replacement, supply voltage, coil resistance, plug connection, control signal, mounting position, operation of the controlled component and any controller fault messages should be checked.
Frequently asked questions about electrical coils
What is an electrical coil used for in a heat pump?
An electrical coil is used to control an electrical or electromagnetic component. Depending on the configuration, this may be a valve, relay function or another control component within the heat pump.
When should an electrical coil be replaced?
Replacement may be required in case of electrical interruption, short circuit, overheating, damaged wiring, no magnetic effect or incorrect switching of the controlled component.
Does every electrical coil fit every ALPS EXCLUSIVE heat pump?
No, electrical coils differ by series, unit type and application. Always check the article number, voltage, connector, cable length, coil type, mounting position and technical configuration before ordering a spare part.
Can a fault also be caused by the PCB?
Yes, a fault can be caused by the coil itself, but also by the PCB, wiring harness, connector, fuse or controlled component. The complete electrical circuit must therefore be checked.
Can an electrical coil be installed by the end user?
For safe and correct operation, installation should be carried out by a qualified technician. Voltage, connection, control signal, insulation and system diagnosis must be technically verified.
