The Goodman B1141702 Fan Center Relay is a genuine OEM control component engineered for the GUI100-4 gas furnace and other compatible Goodman and Amana heating systems. This fan center combines a 24-volt relay with an integrated transformer terminal block, controlling blower operation in response to thermostat and limit-control signals. When your furnace blower fails to start, runs continuously, or short-cycles, a failed fan center relay is one of the most common culprits.

Specifications

  • Part Number: B1141702
  • Type: Fan center relay (SPDT switching)
  • Coil Voltage: 24V
  • Application: Gas furnace blower control
  • Fits: Goodman GUI100-4 and compatible models

OEM vs. Generic

This is a genuine Goodman OEM part, built to the exact electrical and mechanical tolerances of your furnace. Generic aftermarket relays may cost less up front, but often use lighter-duty contacts that pit and fail prematurely under the repeated switching loads of a furnace blower. Choosing OEM ensures correct coil resistance, contact rating, and terminal layout for a plug-and-play fit.

Installation Difficulty

Moderate — This repair involves working with 24V and line-voltage wiring inside the furnace control compartment. Always shut off power at the disconnect before servicing. Label wires before removal and match them to the new relay's terminals. If you are not comfortable working with furnace wiring, we recommend a licensed HVAC technician.

Backed by genuine Goodman quality. Ships from our US warehouse.

Is this relay compatible with Bryant or Payne too?

The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman relay?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
