Lochinvar & A.O. Smith 100299163 Fuse
The Lochinvar & A.O. Smith 100299163 Fuse is a critical OEM replacement part designed for integration within high-efficiency commercial boilers and water heaters. As a 250V Time Delay fuse with a 0.600 Amp rating, it is engineered to protect sensitive control boards and transformer circuits from sustained overcurrent while allowing for the transient inrush currents typical during startup cycles. This slow-blow fuse prevents nuisance tripping, ensuring that your HVACR systems maintain operational uptime without compromising secondary circuit protection.
When diagnosing low-voltage control issues or "no display" faults in Lochinvar Knight or A.O. Smith Custom Hi-Power units, verifying the integrity of the 100299163 control circuit fuse is a standard protocol. Its time-delay characteristics are essential for stabilizing power delivery to ignition modules and interface displays. Using a genuine 0.6A 250V fuse ensures HVAC system compatibility and maintains the precise electrical tolerances required by the manufacturer to safeguard the internal logic components against thermal damage and spikes.
Key Benefits- Optimized Protection: Precisely rated at 0.600 Amps to shield delicate electronics from overcurrent conditions.
- Time-Delay Functionality: Specifically designed to handle momentary amperage surges during component cycling without rupturing.
- Broad Compatibility: A direct OEM replacement for various Lochinvar and A.O. Smith commercial water heating and boiler series.
- Voltage Stability: Rated for up to 250V, providing a robust safety margin for 120V and 240V control circuits.
What happens if I use a fast-acting fuse instead of this time-delay model?
A fast-acting fuse will likely blow immediately upon the initial inrush current of the transformer or control board, causing repeated system lockouts. This time-delay fuse allows for those brief, normal spikes.
Which Lochinvar models use the 100299163 fuse?
This part is commonly found in the Smart System control panels of Knight boilers and many A.O. Smith commercial electric water heaters as a secondary circuit protector.
How can I tell if this fuse is blown?
Conduct a continuity test using a multimeter. If the circuit is open, the fuse must be replaced to restore power to the user interface or ignition module.
