How Rheem Products Fail – and How We Fix Them

Rheem builds solid furnaces, but every brand has its patterns. After years of working on Rheem systems across San Antonio, we see the same handful of failures repeat. Here’s what actually breaks, what causes it, and what we do about it.

• Rheem Classic Series – ignitor failure. The Classic 90 and 80 lines use a silicon nitride hot-surface ignitor that gets brittle over time. San Antonio’s frequent short-cycling in mild winters doesn’t help. When it cracks, the gas valve opens but nothing lights. We replace it, confirm the gas valve isn’t overfiring, and check the flame sensor while we’re in there. Most ignitor jobs run $150 – $300.
• Rheem Prestige Series – pressure switch tripping. The Prestige RGPE and R96V lines use a condensing secondary heat exchanger that produces acidic condensate. If the drain line clogs with sediment (common in San Antonio homes with older plumbing), the pressure switch opens and the furnace won’t start. We clear the trap, flush the line, and verify the switch isn’t sticking. This is a $200 – $400 fix depending on access.
• Rheem Classic Plus – blower motor capacitor failure. The PSC blower motors on Classic Plus 95s eat capacitors, especially in Attic installs where San Antonio summer heat bakes the unit between furnace seasons. A dead capacitor means the blower hums but won’t spin. We test the microfarad rating, replace with an OEM-spec capacitor, and measure amp draw to confirm the motor is still healthy. Usually $150 – $250.
• Rheem communicating systems – board communication faults. The Prestige R98V and Econet-enabled models can throw error codes when the thermostat loses its pairing with the control board. Sometimes it’s a bad board; just as often it’s a loose molex connector or a power dip from a San Antonio storm. We diagnose rather than guess, and we don’t replace a $400 board when a tightened connection fixes it.
• Heat exchanger concerns on older Rheem 80% furnaces. On Classic 80 units past their fifteenth year, we occasionally find small cracks at the weld seams. It’s not a Rheem design flaw, it’s age and thousands of heating cycles. If we find a crack, we show you the borescope photo, explain the carbon monoxide risk plainly, and quote a replacement rather than patching something that shouldn’t be patched.

Our Rheem Furnace Repair Process

Every Rheem job follows the same sequence. No shortcuts, no mystery pricing.

1. 1
   You call, a person answers. 24/7, not a voicemail tree. You describe the symptom: no heat, short cycling, banging, or a code on the thermostat.
2. 2
   We send you the tech’s name and photo before arrival. You know exactly who’s walking up your driveway. At the door, they show ID.
3. 3
   Diagnostics come first. The tech pulls the error code, tests the component (gas valve, ignitor, pressure switch, blower motor), and finds the root cause, not just the symptom.
4. 4
   You get a written price before work starts. Parts and labor, one number. You approve it or you don’t. No work begins until you do.
5. 5
   The repair happens with the right part. We use OEM Rheem parts when the warranty or system age calls for it, and quality aftermarket parts when it doesn’t matter. We explain the difference honestly.
6. 6
   We test, clean up, and hand you a written guarantee. Every repair is covered for 365 days under our Done Right Promise. If it fails, we return free.
