Rheem Parts - Keep Your Home Heating & Cooling Systems Running Longer

Rheem has been one of the most trusted names in home comfort for decades, manufacturing dependable furnaces, air conditioners, heat pumps, and water heaters for residential and commercial applications. Designed for long-lasting performance, these systems still experience normal wear over time as components such as flame sensors, igniters, run capacitors, and control parts gradually reach the end of their service life.

At BlueStars Parts, you'll find a wide selection of Rheem parts, including Rheem furnace parts, Rheem air conditioner parts, and Rheem water heater parts, all designed to meet OEM specifications for reliable fit and dependable performance. Whether you're restoring heat in the winter or keeping your cooling system running efficiently through the summer, the right replacement part can help extend the life of your equipment while avoiding unnecessary replacement costs. 

Common Signs You Need Replacement Parts

These are the warning signs that typically point to a specific failed component rather than a full system breakdown:

• Furnace cycles on but shuts off shortly after ignition, repeatedly
• Furnace won't ignite at all despite the thermostat calling for heat
• Pilot light won't stay lit, or goes out shortly after being manually lit
• AC unit or heat pump hums when starting but doesn't reach full operation
• HVAC system cycles on and off rapidly without maintaining set temperature
• Fireplace pilot assembly won't hold a flame or ignites intermittently
• Furnace error codes pointing to flame sensor or igniter failure
• Air conditioner fan runs but compressor doesn't engage under load

Shop by System Type

Browse by home system to find the right part category for your repair:

• Furnace: Flame sensors, hot surface igniters, and control components for ignition and safety-shutoff issues
• Air Conditioner / Heat Pump: Run capacitors, start capacitors, and fan motor components for startup, cycling, and airflow problems
• Fireplace / Gas Appliances: Pilot assemblies, thermocouples, and gas valve components for pilot-light and ignition issues
• Water Heater: Thermostats, heating elements, and anode rods for temperature and efficiency problems
• General HVAC: Capacitors, sensors, and control components that span multiple Rheem and Ruud system families

Popular Rheem Replacement Parts

These are the parts our customers order most often for Rheem and compatible HVAC system repairs:

• 62-23543-01 Furnace Flame Sensor Replacement — For Rheem Ruud WeatherKing Thermal Zone DuroGuard Furnace (2-Pack)
  When a Rheem furnace ignites but shuts off within a few seconds of starting, a dirty or failed flame sensor is almost always the cause — this 2-pack replacement restores reliable flame detection and keeps the burner running through a full heat cycle.
• 62-22868-93 Furnace Ignitor Hot Surface Igniter
  If your Rheem furnace clicks through its startup sequence but never actually fires, a cracked or burned-out hot surface igniter is the most likely culprit — this direct-fit replacement restores reliable ignition without requiring a service call to diagnose.
• 10002264 Natural Gas 3-Way Pilot Assembly Kit — For HHT Majestic Monessen Temco Vermont Castings Fireplaces, SRV10002264 LP NG 3-Way Pilot with Thermocouple
  When a gas fireplace pilot won't stay lit or the thermocouple has failed, replacing the full pilot assembly is the most reliable fix — this 3-way kit supports both natural gas and LP configurations across a wide range of compatible fireplace brands.
• 40+5 uF MFD 370/440 VAC Round Dual Run Capacitor — For Air Conditioner, Heat Pump
  When a Rheem AC unit or heat pump hums at startup but the compressor or fan won't engage, a failed dual run capacitor is one of the most common and inexpensive causes — this 40+5 µF replacement supports both fan motor and compressor circuits in a single unit across dual-voltage systems.

How to Choose the Right Part

HVAC and heating parts require a precise spec match - here's what to check before ordering:

• For furnace parts, locate the model and serial number on the data plate inside the furnace cabinet door — not on the exterior housing or thermostat
• For flame sensors and igniters, confirm the furnace model series before ordering, since connector types and mounting configurations vary across Rheem furnace generations
• For run capacitors, always match the µF rating and voltage exactly — using the wrong capacitance value can damage the compressor or fan motor
• For pilot assemblies, confirm whether your fireplace runs on natural gas or LP before ordering, and check the pilot tube configuration (1-way vs. 3-way)
• Match your specific symptom — short cycling, no ignition, pilot outage, or AC startup failure — to the most likely failed component before adding to cart
• Contact our support team with your system model number and error code if you want a fitment check before placing your order
