Blower motor resistors and high-temp BMR kits are manufactured in our IATF 16949-certified
North American facilities.
In addition to our full line of the highest quality Standard®, Blue Streak® and Intermotor® blower motor resistors, we’ve engineered a line of problem-solving, high-temp connectors and kits.
Our Engineers sample-test every blower motor resistor for draw, resistance, and RPM. Test samples are validated to precisely match the OE specs and meet or exceed the OE for durability. We examine performance at all speeds, and then conduct 48-hour load tests.
It’s how we know our blower motor resistors will operate at peak performance and deliver a long service life under all operating conditions.
We improved on the original, engineering a high-temp connector that withstands excessive heat and the extreme current that can melt an inferior resistor or connector.
Kanthal D resistor wire provides longer life for higher watt resistors
Precision-built resistor coils for better fan control
Tin-plated steel terminals ensure maximum contact and excellent fit
Made from high-quality ceramics with copper electrical connectors for accurate resistance values
Thermally protected with on-board fuse
Thermal-cycle tested -22°F to 257°F
TXL copper wiring withstands high electric current to protect against heat-related failure
High-temp connector prevents melting under extreme temperatures
Our RU631 Blower Motor Resistor features several improvements over the OE, including an umbrella cover design that prevents water intrusion and a larger-output power device and upgraded two-ounce copper board that protects against overheating.
Larger output power device mounted directly to heat sink improves heat dissipation
Improved umbrella cover design prevents condensation from entering module
RTV sealant around heat sink and cover perimeter prevents water intrusion
Manufactured in the USA
Upgraded 2 oz. copper board increases conductivity and power dissipation to prevent overheating
Included wire harness undergoes voltage drop testing to ensure performance
Be sure to inspect the mating connector for signs of damage caused by excessive heat. If damaged, replace with a problem-solving Blue Streak® blower motor resistor kit or a premium Standard® connector.
For more than 100 years, when the OE failed, technicians trusted Standard®, Blue Streak® and Intermotor® to deliver
a part that’s equal to or better than the original it’s replacing.
