What Fault 28 Means
Fault 28 is raised against the ice maker's water solenoid when it draws more current than expected. F&P's procedure is to inspect the connections to that solenoid and measure its resistance, correcting any loose connection and replacing the solenoid if the reading shows it has failed.
Common Causes of Fault 28
- A shorted turn in the solenoid coil
- Water or corrosion bridging the solenoid terminals
- Damaged wiring shorting the solenoid circuit
🔧 One Safe Check You Can Try
If you can reach the supply valve for the refrigerator's water line, closing it is a sensible precaution while you wait, since a solenoid circuit in trouble is one you would rather not leave able to open.
⚠ Why You Shouldn't Go Further Than That
- Shut the water supply off and unplug the appliance before anything is touched, in that order, because this is a mains-powered valve sitting in a plumbed connection.
- A coil drawing over-current can also have damaged the module output driving it, and only testing both establishes what actually needs replacing.
- Compression fittings on the fill line seal once; disturbed and re-made by hand they weep slowly behind the cabinet where nobody sees it.
- Guessing between a failed coil and a failed driver means a fair chance of paying for a part that was working.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
