How Lennox Products Fail – and How We Fix Them
Not all furnaces break the same way. Lennox builds solid equipment, but after enough cycles in Florida’s salt-heavy coastal air and the occasional cold snap that pushes a system to run longer than it’s used to, certain patterns show up. Here’s what we see most often on Lennox furnaces in West Palm Beach homes:
- Ignitor failure on the Elite series (EL195, EL296) – The silicon nitride ignitors on the Elite line are generally reliable, but when they do fail, the furnace will click on, run the draft inducer, and then just sit there with no flame. Homeowners describe it as “the furnace is trying but nothing happens.” We replace the ignitor with the correct Lennox-specified part and verify the flame sensor while we’re in there, since a marginal flame sensor often follows an ignitor replacement by a few weeks. Honest fix: $150 – $300 parts and labor.
- Pressure switch nuisance codes on the SLP98V – The SLP98V is a modulating furnace with a lot of brains, and its pressure switch circuit can throw false “pressure switch open” codes when the condensate drain line gets partially clogged. In West Palm Beach’s humid air, condensate lines accumulate algae and sludge faster than almost anywhere else in the country. We don’t just swap the switch and leave; we clear the drain line and test the switch under load. The switch itself is rarely the root cause, and we’ll tell you that before we sell you one.
- Control board failure on the G61 and G61MPV (older Merit/Elite-era units) – These boards are now aging out in a lot of West Palm Beach homes, and they fail in a specific way: the furnace throws a 4-flash code, or the blower runs constantly while the burners won’t fire. The boards are still available, and we install OEM replacements when the furnace is otherwise in good shape. But if your G61 is also showing heat exchanger rust from years of Florida humidity cycles, we’ll tell you honestly whether a board replacement makes sense or whether you’re better off putting that money toward a new system.
- Blower motor capacitor and motor wear on the ML180/ML193** – The Merit series is Lennox’s budget line, and the PSC blower motors they use wear out bearings and capacitors on a predictable schedule. You’ll hear it first: a hum that turns into a rattle, or a blower that starts slow and gradually comes up to speed. We can often save the job with a capacitor replacement for under $200. If the motor itself is shot, we’ll give you a fixed price for the motor and a realistic conversation about whether the rest of the furnace warrants the investment.
- Heat exchanger stress on the EL280 in salt-air neighborhoods – West Palm Beach homes near the Intracoastal deal with more than humidity. Salt in the air accelerates corrosion on any exposed metal, and furnaces in neighborhoods like Northwood Hills, El Cid, and Southland Park often show heat exchanger rust sooner than the same unit would in Orlando. We’ll inspect the heat exchanger on every repair call, and if we find cracks or corrosion, we’ll show you photos and give you a real repair-versus-replace number, not a scare tactic.
The pattern here is simple: Lennox makes good furnaces, but the parts that fail are usually diagnosis problems more than they are replacement problems. A company that swaps parts until the problem goes away costs you money. We find the problem once and fix it once.
Our Lennox Furnace Repair Process
When you call (728) 220-0996 for Lennox furnace repair in West Palm Beach, here’s how the job actually goes:
- 1
You call, a person answers. No phone tree, no “press 2 for service.” You describe the symptom, and we schedule a window that works. Before the technician arrives, you’ll get their name and photo by text or email.
- 2
We diagnose before we quote. The technician checks the error codes, tests the ignitor, pressure switch, flame sensor, and gas valve, and watches the full startup sequence. A Lennox furnace’s startup sequence is specific, and skipping steps means misdiagnosis. We don’t skip steps.
- 3
You get a written price. Before any tool touches a part that costs money, you’ll see the number on paper. The price includes parts, labor, and the exact scope of work. You approve it, or you don’t, and either way you pay us the diagnostic fee and that’s the end of it. No pressure.
- 4
We make the repair with the right parts policy. Where the furnace is under Lennox warranty, we use OEM parts and handle the warranty paper for you. Where it’s not, we’ll offer OEM or a quality aftermarket equivalent and explain the difference in plain language. We never install a mystery-brand part to pad the margin.
- 5
We test, then we walk you through it. After the repair, we run the furnace through full cycles, verify the flame looks right, the blower sounds right, and the safety switches all do their jobs. Then we show you what we did and why.
- 6
You get the guarantee in writing. Every repair carries our 365-Day Done Right Promise: if the repair fails within a year, we come back and make it right at no charge. And if anyone arrives at your door who you weren’t told to expect, that visit is on us and we make it right. That’s the Threshold Verified standard.

Why West Palm Beach Homeowners Call Brandt HVAC Co West Palm Beach for Lennox Work
Devin Marlowe grew up in Los Angeles and learned refrigeration and HVAC at Los Angeles Trade-Technical College, doing the work with his hands, not from a slide deck. He’s been fixing heating and cooling systems for more than two decades, and for the past several years his crew has been the team West Palm Beach turns to when a furnace acts up, including plenty of jobs in the Northwood Hills neighborhood where a heating failure on a cold Florida night is not a small problem. He’s known for giving a straight answer before a price, and for not recommending a replacement when a repair will honestly do the job. His rule with your furnace: “Tell me what it’s doing, and I’ll tell you what it needs – no guesswork, no runaround.”
When you call Brandt HVAC Co West Palm Beach, you get a live person on the phone at 2 a.m. if that’s when the house goes cold. You get a technician whose name and photo you see before they arrive, who shows a badge at the door, and who works under a written guarantee. We service Lennox, and we also fix Carrier and Trane, so you’re not locked into one brand’s answers. The name Brandt comes from an old word for a firebrand, and keeping a home warm is exactly the work we do.
FAQs
No. Your Lennox warranty is tied to the equipment, not the repair company, as long as the work is done properly and the parts meet Lennox’s specifications. As an independent Lennox service provider, we use OEM parts where your warranty requires them and handle the warranty paperwork for you. The only way to void the warranty is neglect, improper installation by whoever put it in, or a repair that doesn’t meet spec. That last one is why you want a company that actually understands Lennox systems.
Most calls are dispatched same-day or next morning, and we staff phones live 24/7 so you’re never leaving a voicemail and waiting. If you call at 11 p.m. on a Saturday because the furnace won’t light and the house is dropping below 60, a real person answers and gets a technician moving. For non-emergency diagnostics, we’ll schedule a specific window and you’ll know who’s coming before they’re in the driveway.
The honest answer depends on three things: the age of the unit, the condition of the heat exchanger, and the cost of the repair relative to the remaining life. A $300 ignitor on an 8-year-old Elite series is almost always worth fixing. A $600 control board on a 16-year-old furnace with a corroded heat exchanger is often not, because the rest of the system hasn’t got much life left either. We’ll show you the evidence and give you both numbers, then leave the decision to you. Call (728) 220-0996 and we’ll give you a straight read.
Intermittent operation on a Lennox furnace usually points to a pressure switch that’s on the edge of its spec, a flame sensor that’s borderline, or a condensate drain that’s partially clogged and only backs up sometimes. These are the most common West Palm Beach failures because our humidity moves in and out, always. A failing pressure switch or partially blocked drain can cause exactly this: fine one cycle, dead the next. We diagnose intermittent problems carefully because the worst thing you can do is replace a part, have the furnace work for a week, and then leave for work on a cold morning with no heat. The 365-day guarantee means if we fixed the wrong thing, we come back and fix it right at no charge.
We keep common Lennox repair parts on our trucks – ignitors, flame sensors, pressure switches, capacitors, and the boards that fail most often on the Merit, Elite, and Signature lines we see all over West Palm Beach. For less common parts, we source from local supply houses in Palm Beach County and can typically have what we need the same day or by morning. When the part is covered under your Lennox warranty, we handle the claim so you don’t have to.
If your Lennox furnace is acting up and you want an honest diagnosis, a written price, and a technician you’ve already seen by name and photo before they knock, call Brandt HVAC Co West Palm Beach at (728) 220-0996. Estimates are free, and the person who answers is a real person, every time.
