Solenoid Coil Repair
Arnold has been manufacturing and repairing solenoids/coils since the 1960’s. During this time, we have built and refurbished units that have gone into many different applications such as oncology for medical equipment to radar systems for both civilian and military platforms to university experiments.
A typical solenoid coil repair begins by sending in your unit for evaluation (See figure 1). When a unit is received at our facility, it is tested per the specifications which can include the following:
- Insulation test
- Magnetic field
- Resistance
- Hydrostatic test on cooling system
If the unit can be economically repaired, a repair quote is submitted. Once the order is received, the Arnold Team disassembles the unit (see figure 2).
All components that are reusable are then refurbished to new condition (see figure 3) and unusable parts are replaced.

The rebuilt unit is tested again for the previously mentioned items to verify that it meets all specifications (see figure 4). The refurbished unit will carry the same one-year warranty as a new unit.
Repairing a unit has many factors that go into the cost of the final repair. The larger factors that go into determining the typical repair price are:
- The number of individual coils that make up the unit
- What material unit is made of – foil or wire, aluminum or copper
- How much reconditioning is required and possible on the components
- What needs to be replaced
The following is an estimate for typical repairs:
| Outside Diameter | Length | Weight | Repair Price | |
|---|---|---|---|---|
| 10" | 12" | 250 lb | $10,250 | |
| 18" | 18" | 750 lb | $16,500 | |
| 50" | 48" | 7000 lb | $90,000 |
