Pellet Stove Repair in Brentwood: Written Report, Licensed Technicians

The call came from a homeowner on the Kanan Dume corridor in Brentwood whose pellet stove had stopped igniting mid-January. She'd run it regularly through December with no issues. Then the Santa Ana winds hit, three straight days of hot, dry gusts blowing debris across the hillside. Ash, grit, and dried chaparral fragments packed the exterior cap and worked into the combustion air intake. She described the stove clicking like it wanted to start, the auger motor turning, pellets dropping into the burn pot, but no flame. She assumed the igniter had died. She was partly right.

What worried her most was the smell. A faint, acrid odor whenever the blower kicked on. That's a sign we take seriously because it often means the combustion blower is straining against a blocked exhaust path. In canyon-exposed homes like those along Latigo Canyon and the Kanan Dume corridor, Santa Ana events push fine debris past damaged or poorly sealed chimney caps. A pellet stove's venting system is far less forgiving than an open fireplace. Even a partial blockage changes exhaust pressure enough to prevent ignition, and running the stove in that state risks carbon monoxide spillage. We scheduled a visit for the next morning. Before touching the stove, we'd need to inspect the full vent run and cap. A routine chimney inspection catches these problems before they strand you without heat.

We started outside. The chimney cap had a mesh screen clogged with wind-driven debris, dried leaves, and fine sand typical of Encinal Canyon and the broader Kanan Dume corridor during Santa Ana season. The cap itself had shifted slightly, likely from repeated wind stress on a fastener that had corroded over several seasons. Per NFPA 211 standards, we performed a Level 2 inspection using a camera to check the full vent liner. No cracks, no separation at the joints, but significant buildup narrowing the exhaust path by roughly 30 percent. That restriction was enough to trip the stove's pressure sensor and block ignition. We cleared the vent, reseated and re-fastened the cap with stainless hardware rated for coastal and canyon exposure.

Inside, the igniter had in fact failed. Pellet stove igniters in Brentwood homes that see intermittent use tend to last three to five seasons. Hers was on year four. We replaced it, tested the auger motor draw (within spec), confirmed the combustion blower was pulling correctly with the vent now clear, and verified the control board wasn't throwing error codes. The stove lit on the first cycle. We also recommended a chimney sweep before next season to clear any residual buildup in the lower vent section. If your pellet stove carries an EPA certification, maintaining clean venting isn't optional. It's what keeps the stove operating at the efficiency and emission levels it was rated for.
