How Rheem Products Fail – and How We Fix Them

Rheem builds solid furnaces. The classic Rheem 90 Plus and newer R96V and R98V lines are common in Los Angeles homes, and each has failure patterns we see year after year. Here’s what actually breaks and what we do about it:

• Ignitor failure on the classic 90 Plus line. The silicon nitride hot-surface ignitor in older Rheem 90 Plus furnaces gets brittle after 8 – 12 years. When it cracks, the furnace tries to start, the gas valve opens, but nothing lights. The control board then locks out after three attempts. We keep OEM-grade Nitride ignitors on our trucks because the $19 aftermarket copies fail in months, not years.
• Pressure switch faults on R96V models. Rheem’s variable-speed R96V has a rubber diaphragm inside the pressure switch. In Los Angeles, dust from dry inland air works past the filter and coats that diaphragm, causing nuisance trips – the furnace shuts down like the vent is blocked when it isn’t. Our fix is a real diagnosis: we check draft with a manometer before replacing anything.
• Inducer motor bearing whine. Rheem inducer motors move exhaust gas out of the heat exchanger. On many units entering their second decade, the bearings start howling before the motor seizes entirely. It’s a sound homeowners describe as a jet engine spooling up. We replace the inducer assembly with an OEM or Fasco replacement and balance the new inducer to spec.
• Control board failures on R98V modulating furnaces. The R98V is Rheem’s high-end modulating furnace, and its main control board is the single most common part failure. The symptom is often a blank display or a furnace that runs the blower constantly but never fires. We carry updated board revisions from Rheem’s supply chain – not pulled-from-scrap eBay boards – and check the thermostat wiring before condemning the board, since a crossed low-voltage wire can mimic the same failure.
• Flame sensor buildup on every Rheem line. This one isn’t brand-specific, but it’s the most common Rheem furnace repair call we run across Los Angeles. The flame sensor is a thin metal rod that sits in the burner flame to confirm ignition. When it gets a gray coating of silica from L.A.’s dry air, the furnace lights, runs for four seconds, then shuts down. The fix is a cleaning with a fine abrasive pad, not a wipe with sandpaper, which can gouge the rod and ruin it. If it’s beyond cleaning, a new sensor is a $35 part and a five-minute install.

Our Rheem Furnace Repair Process

When you call Dalton Heating & Air for a Rheem furnace repair in Los Angeles, here’s exactly how the job runs:

1. 1
   You call and reach a person. Not an answering service, not a call-back queue. We take your address, your furnace’s symptom, and your availability. If it’s cold out and you’re without heat, we move you up the schedule.
2. 2
   We arrive inside the window. Our technician is background-checked and in uniform. Marco Benitez and the team have worked on Rheem equipment across the LA Basin for over two decades, so the unit will get opened with purpose, not hesitation.
3. 3
   We diagnose before we quote. That means checking gas pressure, static pressure, flame signal, and safety switch operation – not throwing parts at the problem. Whatever we find, the price goes in writing before any work starts.
4. 4
   We use the right parts. Rheem equipment runs best on Rheem OEM components. For older systems where OEM parts are discontinued, we use industrial-grade aftermarket parts from suppliers we trust, and we tell you what you’re getting before we install it.
5. 5
   We test the complete system. After the repair, the furnace must light, run, cycle, and shut off correctly – not just once, but through a full heating cycle. We check the temperature rise across the heat exchanger to make sure it’s operating inside Rheem’s spec.
6. 6
   You get a written guarantee. The repair is covered in writing for a full year. If that same repair fails inside that window, we come back at no charge. That’s not an upsell; it is the baseline on every Dalton Heating & Air job.

Why Los Angeles Homeowners Call Dalton Heating & Air for Rheem Work

Most of our Rheem furnace repair customers in Los Angeles have been burned before. They had a technician no-show, or quote one price on the phone and another at the door. We run differently because we’re held to The Garrison Standard, a code our crews have worked under since 2003. That means you get a written price before any work begins, on every job. You get a written guarantee on every repair, not as an add-on. If the work doesn’t hold, we return at no charge.
