Pellet Stove Repair

A pellet stove is the most electromechanical appliance in the house, and that's exactly why it breaks in ways a wood stove never does. Five systems have to hand off in sequence every time it lights — 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 moves heat into the room. When any one link fails, the board refuses to proceed and the stove either won't light or locks out mid-burn. Texas Service Experts diagnoses these faults to the component, focused on getting the right part right the first time instead of throwing boards at a no-heat call — and because it's the same whole-home crew, the vent and venting the stove depends on get a look too, not just the part that failed.

The control board, not the parts bin, is where diagnosis starts. We read the stored error or status code and trace it: a no-ignition code points to the igniter element, the auger feed, or the hopper; a flame-loss or shutdown code points to the combustion blower, the vacuum/pressure switch, or a fouled exhaust path; an over-temp or fan code points 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. How this differs from pellet-stove-installation: install builds the vent, runs the circuit, and commissions a brand-new stove, while repair never touches the vent route — it isolates and replaces the failed part inside a unit that already passed commissioning.

Behind a large share of repairs is fly-ash, the silent driver — which is why we treat deep-cleaning as part of the fix rather than 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.

A test-burn and an honest repair-versus-replace call close out every repair. 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 quote parts and labor as line items 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 one season, we'll tell you plainly that a new stove is the better spend.
