Product Overview
The DRWH-24 is a wire harness manufactured by Detroit Radiant Products for Re-Verber-Ray DR series infrared heaters equipped with the MARK 10DX-24 control board. It provides the low-voltage electrical connections between the MARK 10DX-24 circuit board and the heater's ignition and sensing components. A failed or damaged harness typically presents as intermittent ignition faults, no-heat conditions, or nuisance lockouts on affected DR series heaters; replacing the harness restores proper signal continuity between the board and downstream components. The manufacturer product page lists this harness as 24V, while the DR Series service manual (LIODR_DR-Series-Manual_23014_10-25) lists the same part number at 25V; verify the correct voltage against the heater's wiring diagram before installation.
Fits Re-Verber-Ray DR series heaters that use the MARK 10DX-24 circuit board. This part is also cataloged under alternate numbers 1FEK8 and 6366574, both of which appear on the manufacturer's own parts listing for the DR series; when cross-referencing from a parts list or distributor search, these numbers resolve to the same assembly. The manufacturer product page lists compatibility broadly as "DR MODELS" without a BTU-specific breakdown, and a BTU-level fitment list was not available at time of publication. See the Fitment panel for the full model list. If it is unclear whether a specific DR model uses the MARK 10DX-24 board, check the label on the existing control board or call with the model and serial number before ordering; confirm fitment against the heater's model and serial tag before ordering.
The part ships as a single harness assembly.
Shut off the gas supply and disconnect power to the heater before beginning any service work. A qualified technician should perform the replacement and verify ignition and sensing operation after installation. No dedicated install sheet was available for this part at time of publication; consult the DR series service manual for wiring procedures and torque specifications.
