Pellet Stove Repair in Encino: Written Report, Licensed Technicians

The call came from a homeowner on a ridgeline property above Coldwater Canyon, one of those 3,500-square-foot estates built in the early 2000s with a pellet stove tucked into a finished basement den. She told us she'd been smelling something acrid near the unit for about a week, even though she hadn't turned it on since February. With wildfire season approaching along the Mulholland Drive corridor, she wasn't taking chances. Her concern was specific: ash and particulate from a nearby brush clearing had been drifting across her property, and she wanted to know if debris had entered the venting system or if something inside the stove itself was failing. She'd already checked the hopper and found it empty, so the smell wasn't burning pellets.

When we arrived, the situation was more mechanical than environmental. The combustion blower was seized. A thin layer ofite calcium-ite calcium builite calcium calcium calcium calcium calcium calcium calcium calcium calcite calcium calcium calcium calcium - let me correct: a thin layer calcium calcium. Calcium calcium buildup from regional hard water condensation had corroded the blower motor's bearings over two idle seasons. This is common in Studio City hillside homes where temperature swings between canyon shade and direct sun create condensation inside venting runs. The auger motor also showed early wear on its drive gear, which would have caused feed failures within weeks of her next cold-weather use. She needed both components addressed before fire season made outdoor access to her vent termination risky. We scheduled the full repair for the following morning.

We pulled the combustion blower assembly and confirmed the bearings had failed from corrosion, not just wear. The control board was throwing an E3 fault code on startup, which pointed to airflow loss from the dead blower rather than a board-level failure. That saved her an unneeded part. We replaced the combustion blower, tested igniter draw at 3.2 amps (within spec for her Harman unit), and cleared calcium deposits from the exhaust path. The hopper sensor tested clean. Per NFPA 211 standards, we performed a Level 2 visual and camera inspection of her venting system from the stove collar to the exterior termination point. No cracks, no separation at joints. The vent cap screen had trapped some leaf debris but no fire-blown particulate, which was her original fear.

For homes along the Hidden Hills border and ridgeline properties near Mulholland Drive corridor, we recommend pellet stove service before October every year. Wildfire proximity means your exterior vent terminations collect airborne ash and debris that can restrict airflow, trip pressure sensors, or clog combustion air intakes. A seized blower or failed igniter during a cold January night is inconvenient. A venting blockage during red flag conditions is dangerous. Estateguard Chimney Care performs CSIA-standard diagnostics on all pellet stove components: auger motors, igniters, control boards, combustion blowers, and hopper sensors. If your stove hasn't been inspected since last season, book a diagnostic visit before conditions change. You can verify your unit's efficiency rating through EPA certified pellet stoves listings.
