Common Failure Symptoms Solved by SF-HVC-106

Technicians and property owners typically replace 7000BMVR when experiencing one or more of the following failure modes:

  • Pilot stays lit with strong thermopile voltage (>450mV) but main burner gas valve never opens
  • Gas valve knob stuck or refusing to hold pilot magnet down
  • Intermittent main burner dropout during thermostat call

Step-by-Step Dimensional Verification & Installation Notes

Test thermopile output under load across TH-TP and TP terminals first (must hold >180mV with thermostat jumped). Shut off main gas supply, apply pipe-thread sealant to male NPT threads only, and soap-test for leaks.

Frequently Asked Technical Questions (7000BMVR)

Where is the casting or OEM part number (7000BMVR / 720-400 / 7200ER) stamped on this part?

On Robertshaw / Uni-Line assemblies, look for the stamped or die-cast numbers (7000BMVR, 720-400, 7200ER, 700-506, 710-502, RS-7000BMVR) on the underside of the metal housing, along the link arm, on the stainless hinge track, or printed on the circuit board/valve label. Note that casting numbers identify the housing casting, so always confirm critical dimensions (1/2" x 3/4" NPT inlet/outlet (includes reducer bushings); 3.5" WC Natural Gas regulator (LP conversion kit compatible); 250–750mV) as well.
