TP-851 Diagnostic Circuit Board

The Re-Verber-Ray TP-851 is a Micro-60-24 diagnostic circuit board that serves as the ignition and diagnostic control module for Re-Verber-Ray gas-fired tube heaters. It operates on 24/120V. The board manages and monitors the heater's ignition sequence and reports fault and status conditions used for troubleshooting. It is the control module referenced in the parts breakdowns for the heaters it fits, seated in the control compartment and wired to the inducer, gas valve, and sensing components per the unit's wiring diagram.

The TP-851 is used on the RVA-2, HL-2, and LD family of units (24/120V); see the Fitment panel below for the full model list. The manufacturer's parts store also lists Alt Part # 2020-52 (also referenced as "Channel 2020-52" / 202052) as the same item under a distributor designation. No separate OEM (non-Re-Verber-Ray) manufacturer cross-reference was found in the cached documentation; confirm with Re-Verber-Ray or the distributor before treating 2020-52 as a guaranteed drop-in equivalent. Related boards such as TP-851B and TP-851C are used on other Re-Verber-Ray series (CL3, CX3, DSRF, DSRL, DSRS, DST, DX3L, HL3, LD3, LS3) and are not interchangeable with the TP-851; match the board revision to the model's parts breakdown before ordering.

The TP-851 ships as the bare board only. Wire harness and mounting hardware are not included unless listed separately by the model's parts breakdown.

As with all heater control-board work, shut off gas and disconnect power before servicing, verify wiring against the unit's installation sheet, and have a qualified technician confirm proper ignition operation after replacement. No install sheet or datasheet was found in the cached documentation for this part; consult the unit's own installation manual for wiring detail.
