Pellet Stove Repair

The pellet stove is the most electromechanical appliance in the house, which is exactly why it fails in ways a wood stove never does. Every light-off is a five-system handoff in sequence — the auger meters pellets, the igniter heats the burn pot, the combustion blower establishes exhaust flow, a vacuum or pressure switch confirms that flow, and the control board orchestrates the whole startup before the convection fan ever pushes heat into the room. Break any one link and the board refuses to proceed: the stove won't light, or it locks out mid-burn. We diagnose these faults down to the component, holding the premium standard of getting the right part right the first time instead of throwing boards at a no-heat call.

Diagnosis begins at the control board, not the parts bin. We read the stored error or status code and trace it: a no-ignition code sends us to the igniter element, the auger feed, or the hopper; a flame-loss or shutdown code to the combustion blower, the vacuum/pressure switch, or a fouled exhaust path; an over-temp or fan code to the convection blower or its sensor. Pellet igniters are wear items that fail every few seasons, auger motors seize or shear, and blowers grind their bearings out — but the symptom rarely names the culprit, so we test each link rather than guess. Unlike pellet-stove-installation, which builds the vent, runs the circuit, and commissions a brand-new stove, repair never touches the vent route — it isolates and replaces the failed part inside a unit that already passed commissioning.

Fly-ash is the silent driver behind a large share of repairs, which is why we fold deep-cleaning into the fix rather than tack it on as an upsell. Pellet exhaust packs fine ash into the burn-pot holes, the heat-exchanger passages, the exhaust path, and the area around the combustion blower and the vacuum-switch port. That buildup starves the burn of air, which overworks the igniter and blower and trips the safety switch into a lockout — so a 'failed' switch or a 'weak' blower is often a clean stove away from working. We clear the ash the diagnosis points to, so the replacement part isn't fighting the same restriction that killed its predecessor.

Every repair closes with a test-burn and an honest repair-versus-replace call. We run the stove through a full light-off, hold it through steady-state, and confirm the combustion and convection blowers, the auger feed, and the safety switches all behave across the cycle, with an ambient CO check before we leave. We line-item parts and labor so the math is yours: a single igniter or blower on a healthy stove is an easy yes, but when a fifteen-year-old unit starts stacking board, auger, and blower failures in a single season, we'll tell you plainly that a new stove is the better spend.
