Lochinvar & A.O. Smith 100208232 Fuse
The Lochinvar & A.O. Smith 100208232 Fuse is a critical 5 Amp OEM replacement component designed specifically for the protection of high-efficiency boiler and water heater control modules. This 5 x 22mm time-delay fuse (also cross-referenced as FUS2002) is frequently utilized in Power-Fin and Knight series units to safeguard pump relays, ignitor outputs, and blower motor circuits from overcurrent conditions. Rated for 250V, this slow-blow fuse ensures that transient surges during startup do not cause nuisance trips while providing reliable circuit interruption during genuine electrical faults. As a veteran technician, you know that using a standard fast-acting fuse in these boards will lead to immediate failure upon inductive load engagement. Always verify the specific fuse position—typically F1, F4, or F5 on the SMART SYSTEM control board—before installation to ensure HVAC system compatibility and optimal boiler circuit protection.
- OEM Precision: Genuine A.O. Smith replacement part ensures exact fitment and resistance specifications for sensitive Lochinvar control boards.
- Time-Delay Functionality: Engineered as a slow-blow fuse to handle the initial inrush current from circulator pumps and combustion blowers.
- Technical Standard: Features a 5A 250V rating with a 5 x 22mm form factor, meeting standard HVACR electrical safety requirements.
- Broad Compatibility: Supports a wide range of models including Lochinvar Shield, Knight, and Power-Fin series boilers.
What happens if I use a fast-acting fuse instead of this time-delay model?
Standard fuses cannot handle the temporary amp spikes when the pump relay or blower kicks on, resulting in immediate "No Display" or "No Operation" faults. Using the correct 100208232 fuse prevents these service callbacks.
Where is this fuse typically located in the system?
In most Lochinvar Knight and Power-Fin units, these are located directly on the main control module behind the access panel, often protecting the 24VAC or 120VAC output legs to peripheral components.
Which error codes indicate a blown 100208232 fuse?
A blown fuse often manifests as a "No Display" condition, "Pump Not Operating", or an "Ignition Failure" if the fuse protecting the ignitor output has opened.
