Why Danfoss MP1 Water Pump control operates pump in one direction only?
- JJeffrey MosesJul 28, 2025
If the Danfoss Water Pump control only operates in one direction, there may be a control coil failure. Measure the resistance at the coil pins. The resistance should be 14.20 ohms (24V) or 3.66 ohms (12V) at 20°C [70°F]. Replace the coil if the resistance is incorrect.
