AS-58386-92 – SHEATH HEATER (RHEEM)

This is a replacement sheath heater element — the actual heating coil inside your electric furnace or air handler. If one element has burned out or broken, your system may still run but won’t heat as well. Replace individual elements as needed.

Specs: 3,500W at 240V / 4,700W at 277V, sheath-style element

Replaces: AS-58386-92

Fits: Rheem: UBHA-14J11SUDA; fits other Rheem and Ruud electric furnaces and air handlers using this element size

Fits these models

• Replacement individual sheath heating element — for repairing a heat kit with one failed element rather than replacing the entire kit
• Verify voltage + kW per element matches your existing strips
• Bring the failed element + heat kit model number to the counter

How do I size a heat kit for my air handler?

Rule of thumb: ~100 CFM per kW of strips. So a 1,600 CFM air handler (4 tons cooling) handles up to about 15 kW. Going beyond your air handler's CFM capacity makes the strips overheat and trip the high-limit. Always verify against your air handler's spec sheet for max kW.

Can I add electric heat to my heat pump system?

Yes — heat pumps almost always use electric strips as backup ("auxiliary heat" or "emergency heat"). The thermostat energizes the strips when outdoor temps drop below balance point (typically 35-40°F in DFW). Match the heat kit to your air handler model.

What does the suffix on the part number mean?

The suffix typically indicates breaker configuration: - BRK = factory breaker included - BR = breakerless (you provide the disconnect) - Other suffixes = circuit count, voltage taps, or thermostat compatibility

How long does an electric heat kit last?

20+ years typical for the kit itself; individual heating elements (sheath heaters) may fail in 8-15 years from cycling. Most kits have replaceable elements — you don't have to replace the whole kit for one bad strip.

Why is my heat kit tripping the high-limit?

Restricted airflow is the #1 cause: clogged filter, dirty blower wheel, undersized return, closed-off supplies. The strips overheat when air doesn't move across them fast enough. Diagnose airflow before condemning the heat kit or limit switch.
