1950-001 Robertshaw Thermopile 36" 250-750 Millivolts MV 2 Lead with PG9 Adapter

Key Features

  • Length: 36 inches
  • Voltage Output: 250-750 Millivolts (MV)
  • Connection: 2-wire spade connectors
  • Function: Pilot generator for self-powered gas control systems
  • Includes: PG9 adapter for pilot burner connection

Replaces / Cross-Reference Part Numbers

  • Robertshaw: 1950-001
  • Series: TP-75

Compatibility & Fitment

  • Designed for gas appliances with standing pilot ignition systems
  • Compatible with gas control valves requiring a 2-wire thermopile with a 250-750 MV output
  • The PG9 adapter facilitates connection to various pilot burner assemblies

When to Replace

  • Pilot light fails to remain lit after the control knob is released
  • Measured millivolt output is low or non-existent
  • Main burner does not ignite or operates intermittently
  • Visible signs of damage, corrosion, or burning on the thermopile tip or leads

Installation Tips

  • Ensure the gas supply to the appliance is shut off before beginning installation
  • Position the thermopile tip so it is fully engulfed in the pilot flame for maximum voltage generation
  • Connect the two spade leads securely to the designated "TH" and "TP" terminals on the gas valve
  • Use the PG9 adapter to mount the thermopile to the pilot burner assembly
  • After installation, turn the gas supply back on and check all connections for leaks with a soap solution

FAQs

The 1950-001 is a pilot generator designed for use on self-powered gas control systems. It is compatible with a wide range of heating equipment, including systems from Robertshaw, Honeywell, White-Rodgers, SIT, Hearth & Home Technologies, and Empire Comfort Systems.
This unit is a versatile replacement for many industry-standard thermopiles. It cross-references with Honeywell Q313A1170, Q313A1170/U, Q313U3000, Q313A1188, Lennox 57P45, Montague 02056-7, Robertshaw 21432, and Uni-Line 1950-C001, among others.
The 1950-001 is rated for 250 to 750 millivolts (mV). It is designed to provide the necessary voltage to operate self-powered gas valves in both natural gas (NG) and liquid propane (LP) applications.
If your pilot light stays lit but the main burner fails to ignite, or if the pilot flame drops out shortly after the gas valve attempts to open, the thermopile may no longer be generating sufficient millivoltage to hold the gas valve open. You can test this using a multimeter set to the millivolt scale while the pilot is burning.
This kit features a 36-inch lead with a two-lead connection and includes the PG9 pilot adapter, which facilitates installation into various pilot burner assemblies.
Before installation, ensure the pilot flame is clean, steady, and properly engulfing the tip of the thermopile. If the pilot orifice is clogged or the flame is yellow and lazy, the thermopile will not heat up correctly, regardless of whether the part is new. Always ensure the gas supply is turned off before beginning any work on the pilot assembly.
