Pellet Stove Repair in Studio City: Written Report, Licensed Technicians

A homeowner on a quiet block near Tujunga Village called us last winter after their pellet stove stopped feeding pellets mid-burn. They'd had gas logs removed from their original 1950s masonry fireplace two years earlier and installed a pellet stove insert in its place. The conversion seemed fine at first. But by the second season, the auger motor was stalling, the igniter wouldn't glow, and the control board was throwing error codes they couldn't interpret. They assumed the stove itself was failing. What worried them most was a faint burning smell near the hopper that appeared every time the combustion blower kicked on.

This is a pattern we see in the Ventura Boulevard flats and along the Moorpark Street corridor, where many mid-century ranch homes were built with masonry fireplaces sized for open wood fires or gas log sets. When a pellet stove gets installed into one of these older fireboxes, the original flue dimensions and liner condition matter more than most installers let on. A flue that worked fine for a gas log burner can create back-pressure problems for a pellet stove's sealed combustion system. That back-pressure strains the combustion blower, overheats the control board, and causes the auger motor to cycle erratically. The homeowner's stove wasn't defective. The venting setup was fighting the appliance. If your pellet stove has been acting up, a <a href='/services/chimney-inspection'>chimney inspection</a> is the right first step before replacing parts.

We started with a Level 2 inspection per NFPA 211 standards, which calls for a camera scan of the full flue interior. The original clay tile liner had two cracked joints about eight feet up from the firebox, right where the old gas log connector had been removed. Those cracks were allowing combustion gases to leak into the chase and letting ambient air dilute the draft. The combustion blower was working overtime to compensate, which shortened the igniter's lifespan and caused the hopper sensor to misread pellet levels. We also found creosote residue (2nd degree, flaky tar deposits) from the previous owner's wood-burning days coating the upper flue tiles. That buildup was narrowing the effective flue diameter by almost an inch. Our CSIA-certified technicians completed a full <a href='/services/chimney-sweep'>chimney sweep</a> before addressing the mechanical repairs.

After clearing the flue, we replaced the failed igniter, tested the auger motor under load, and recalibrated the control board. The cracked liner joints were sealed, and we confirmed proper draft with a manometer reading before reassembling the insert. The stove now runs a full hopper without stalling. For Studio City homes where a gas-log-to-masonry conversion has already happened, we always recommend verifying flue compatibility before the next heating season. Pellet stoves need a tightly sealed exhaust path, and older masonry systems rarely provide one without modification. If you're running a pellet insert in a converted fireplace along the Moorpark Street corridor or anywhere nearby, call Family Home Chimney Experts to schedule a diagnostic visit. You can also review EPA certified pellet stoves to confirm your unit meets current emissions and efficiency standards.
