This page tells Dallas Gelco owners exactly what goes wrong, what it costs to fix, and how we do the work differently.

How Gelco Products Fail – and How We Fix Them

Gelco builds gas log sets, burners, and vented/vent-free fireplace systems that show up in a lot of Dallas homes built or renovated between the late 1990s and the mid-2010s. These are solid products, but every brand has its weak points. Here are the failure modes we see most often on Gelco units in Dallas:

• Gelco vent-free burner pan rust-through. Gelco’s vent-free log sets (we regularly service the Gelco Traditional and Gelco Split Oak series in Dallas homes) sit in an open combustion chamber that draws from interior air. In Dallas, spring humidity and the occasional winter cold snap create condensation cycles inside the firebox. Over years, that moisture settles on the burner pan, and the pan rusts through at the seam where the pan meets the gas inlet. The symptom is a fireplace that lights but produces weak, uneven flames and sometimes a faint gas smell near the floor of the firebox. Our fix: we replace the burner pan with a quality aftermarket pan matched to the Gelco orifice size, or with an OEM Gelco pan when the unit is under warranty. We show you the rusted pan before we replace it.
• Gelco thermocouple failure on gas log sets with pilot assemblies. The Gelco models with standing pilots (especially in vented applications, which are common in Dallas older homes with masonry fireplaces) use a thermocouple that sits directly in the pilot flame. After 8 to 12 years, the thermocouple’s flame-sensing tip degrades, and the pilot won’t stay lit when you release the control knob. This is the single most common Gelco repair call we get in Dallas. The fix is a new thermocouple, typically $145 to $225 installed. We carry common Gelco-compatible thermocouples on the truck.
• Gelco safety pilot assembly (ODS) clogging on vent-free models. Gelco vent-free systems use an Oxygen Depletion Sensor pilot assembly – a small brass tube that measures oxygen and shuts the gas off if the room runs low. In Dallas, where fine dust and pet hair move through homes year-round, that sensor port clogs slowly. The unit starts shutting itself off after 20 or 30 minutes of burn time. Homeowners sometimes mistake this for a gas supply problem. We clean or replace the ODS assembly, test it with a full burn cycle, and explain exactly what that sensor does. Expect $185 to $310 for this repair depending on whether the assembly can be cleaned or must be replaced.
• Gelco gas valve sticking or failing to open on modular fireplace systems. Gelco’s modular gas fireplace systems (the units we see most often in Dallas are installed in homes built in the 2000s with prefabricated chimney flues) use a millivolt gas valve controlled by a wall switch or remote. When that valve sticks – often because of accumulated dust or a failed electromagnet – you’ll hear a click but get no flame. This is not a part to band-aid. We replace the valve with an OEM Gelco valve where warranty applies, or a properly rated aftermarket millivolt valve, and then verify the entire pilot-burner sequence for safety. Valve replacements run $260 to $480.
• Gelco ceramic log deterioration and ember bed breakdown. Gelco’s ceramic fiber logs are durable, but after a decade or more of heating and cooling cycles, the logs begin to lose their surface glaze and the ember bed material (often a mixture of rock wool and vermiculite) breaks down. The fireplace still lights, but the flame pattern looks wrong and the embers no longer glow. Dallas owners often call us thinking the burner is failing when the logs themselves are actually fine. We replace the log set with Gelco-matched ceramic logs or a quality aftermarket set, and pull the old ember material completely rather than layering new over old. Log and ember replacement typically runs $165 to $330.

Our Gelco Gas Fireplace Repair Process

Here is exactly how a Gelco repair works when you call Alcott Chimney Dallas:

1. 1
   You call (361) 264-4483, and a live person answers. No voicemail, no callback queue. We ask what the fireplace is doing (or not doing) and schedule a visit. You’ll get the technician’s name and photo by text before we arrive.
2. 2
   The tech arrives, shows a photo ID badge at the door, and walks you through what we’re checking. At the fireplace, we start with a visual inspection of the firebox, burner, pilot assembly, valve, and any venting components. For vent-free Gelco units, we also check the ODS port and mention the room’s ventilation profile.
3. 3
   Diagnosis and written price before any work. We tell you what’s wrong in plain English, point to the specific part, and give you a written quote. You decide. If the repair can safely wait, we say so.
4. 4
   Parts decision: OEM Gelco vs. quality aftermarket. If your unit is under Gelco’s warranty, we use OEM Gelco parts so your warranty stays intact. If it’s out of warranty, we offer OEM or properly rated aftermarket parts and explain the trade-off honestly. We carry the most common Gelco-compatible thermocouples, ODS assemblies, valves, and burner pans on the truck.
5. 5
   The repair, the test, and the cleanup. We do the work, run a full burn cycle test, check ignition from cold, verify the flame pattern, and confirm the unit shuts down properly. We leave the firebox cleaner than we found it.
6. 6
   Written guarantee and a handshake. Every Gelco repair comes with our 365-Day Done Right Promise: if the repair fails within one year, the second visit is free. Written guarantee, no fine print, every time.

Why Dallas Homeowners Call Alcott Chimney Dallas for Gelco Work

We’ve been repairing Gelco gas fireplaces in Dallas since 2002 as part of the Threshold Group family of home-service companies, and we built our reputation on one thing: you’ll know exactly what you’re paying for. Every technician is background-checked and identity-verified under the Threshold Standard, announced to you by name and photo before arrival, and required to show a photo ID badge at the door. Dallas is full of families where one parent is home alone with young kids, and older homeowners who don’t want to open the door to a stranger. We get that.

We also stock and install the professional trade brands chimney professionals specify: DuraFlex liner systems, HeatShield resurfacing, Olympia Chimney products, Famco components, and Copperfield materials. That means when a Gelco repair reveals a bigger chimney issue – a cracked flue tile, a deteriorating liner, a failing smoke chamber – we fix that too, with the right materials, the same day if warranted. No second appointment, no second strange truck in your driveway.

Ruben Castellano, our owner, trained in trade work at Los Angeles Trade-Technical College and spent years on hands-on chimney jobs across Southern California before bringing that experience to Dallas. He’s known for thorough firebox inspections and for explaining creosote buildup in plain English instead of using it to scare people into unnecessary work. The whole crew operates the same way. Tell you what’s there, tell you what it costs, do the work – that’s the whole job.
