This 632484R rod is built for Nordyne, Intertherm, and Miller units, specifically targeting Frigidaire gas HVAC systems. If your furnace is a Trane or American Standard, this part will not fit your sensor port.

In the listing photo, verify the straight, uncoated stainless steel shaft and the specific wire length. If your current rod has a bent tip or a different wire gauge, this replacement will fail to seat correctly in the burner assembly.

The 903600 model number is the critical identifier here, designed for Intertherm, Nordyne, and Miller furnaces. If your unit is a Carrier or Bryant, this part is the wrong generation and will not align with your flame sensor bracket.

Look at the product image to confirm the wire harness length and the specific threading on the base. A mismatch in the wire length means you cannot reach the control board, and the wrong threading will strip the housing.

This 903600 rod includes a wiring harness and is compatible with Nordyne, Intertherm, and M2/M3/G6 furnaces, replacing parts like 632396 and 632143. If your furnace is a Trane or American Standard, this part is the wrong generation and will not align with your flame sensor bracket.

Examine the photo for the included harness and the specific threading on the base. A mismatch in the wire length means you cannot reach the control board, and the wrong threading will strip the housing.

This Q3400A1024/U assembly is a 24V silicon nitride igniter designed for Q3450, Q3480, and Q3620 valves, replacing R42640-001. If your system uses a standard flame sensor rod rather than a ceramic igniter, this part is the wrong generation and will not align with your flame sensor bracket.

Check the listing photo for the ceramic element shape and the specific mounting bracket. If your current igniter is a metal rod, this ceramic assembly will not fit the housing, and the wrong bracket will prevent secure installation.

This LH680014/LH680534 rod features a 5.7-inch wire length and is a direct replacement for specific Carrier and Bryant models. If your furnace is a Nordyne or Intertherm, this part is the wrong generation and will not align with your flame sensor bracket.

In the photo, measure the visible wire length against your existing part. If your current rod has a shorter or longer wire, this 5.7-inch length will not reach the control board, and the wrong wire gauge will cause a loose connection.

This SEN01114 stainless steel rod is made for American Standard furnaces. If your unit is a Trane, Nordyne, or Intertherm, this part is the wrong generation and will not align with your flame sensor bracket.

Look at the product image to confirm the straight shaft and the specific wire length. A mismatch in the wire length means you cannot reach the control board, and the wrong threading will strip the housing.

This ClimaTek 2-pack replaces Carrier and Bryant LH33WZ517 rods. If your furnace is a Trane, Nordyne, or Intertherm, this part is the wrong generation and will not align with your flame sensor bracket.

Examine the photo for the wire length and the specific threading on the base. A mismatch in the wire length means you cannot reach the control board, and the wrong threading will strip the housing.

This BlueStars Q3400A1024 igniter is designed for Honeywell systems. If your furnace uses a standard flame sensor rod rather than a ceramic igniter, this part is the wrong generation and will not align with your flame sensor bracket.

Check the listing photo for the ceramic element shape and the specific mounting bracket. If your current igniter is a metal rod, this ceramic assembly will not fit the housing, and the wrong bracket will prevent secure installation.

This SEN01114 rod fits Trane and American Standard furnaces, replacing older parts like SEN337 and SEN441. If your unit is a Nordyne, Intertherm, or Carrier, this part is the wrong generation and will not align with your flame sensor bracket.

In the photo, verify the straight, uncoated stainless steel shaft and the specific wire length. If your current rod has a bent tip or a different wire gauge, this replacement will fail to seat correctly in the burner assembly.
