The Copeland Comfort Control (White-Rodgers) 790-707A1 Flame Sensor is a direct OEM replacement flame sensor built to match the Goodman original. The 790-707A1 is the cross-reference for Goodman 0130F00010S, which itself replaced the earlier 0130F00010. On a gas furnace with hot surface ignition, this sensor is the flame proving half of the burner safety circuit. The integrated furnace control (IFC) puts a small AC voltage on the flame rod, the ionized gases in the flame carry that current to the grounded burner, and the rectified DC microamp signal that results tells the board the gas has really lit. No signal, and the control closes the gas valve, which is why a weak sensor shows up as a furnace that lights, runs a few seconds and shuts down.

White-Rodgers built the 790 series to match the OEM bracket, lead connection, length and bend, so the 790-707A1 drops in without bending or cutting. It has a 1/4 in male spade terminal, a straight (180°) rod angle, CSA approval, a rod rated to withstand 2200°F and a 3-year limited warranty. The series uses a Kanthal rod (an iron, chromium and aluminum alloy that resists scale and breakdown), an alumina ceramic insulator and a nickel-plated steel terminal, and each sensor carries a YYWW date code. Other Goodman numbers tied to this sensor include B1172606, B11726-06 and 20488501. The Goodman 0130F00010S is listed for GMP, GMPN, GMS, GMT, GMV, GPD and GPG series gas furnaces, so those are the applications to check first. The 790 family also includes 790-751A1 (Carrier/ICP, 73° bend), 790-801A1 (Lennox, 90° bend), 790-820A1 (Trane) and 790-956A1 (York), each a separate part for a different manufacturer, while 790-843A1 is the universal sensor meant to be bent and cut. The Goodman-matched 789A-707A1 nitride hot surface ignitor comes from the same White-Rodgers lineup.

Before condemning a sensor, put a microamp meter in series with the lead and read it with the flame lit. A reading between 0.1 and 6.0 µA DC is possible, most controls need 0.5 to 1.0 µA to hold the gas valve open, and a healthy sensor reads 2.0 to 5.0 µA. A low reading is often a white silicon oxide film on the rod, which insulates it from the flame. Clean it with very fine steel wool or a piece of paper, finish with an alcohol wipe, and skip coarse sandpaper, because scoring the rod lets the film rebuild faster. Also check the spade connection, a cracked ceramic insulator that grounds the signal, and the burner ground. A rod that keeps fouling points to combustion air contamination. Shut off power and gas, mount the sensor in the original bracket and set the rod in the flame exactly where the old one sat.

Key Benefits

Direct OEM fit: matches the Goodman 0130F00010S bracket, straight rod and 1/4 in spade lead connection, so there is no bending or cutting.
Heat rated for the burner: the Kanthal rod is rated to withstand 2200°F, so it holds up to burner heat and keeps the flame signal stable.
Stable signal path: the alumina ceramic insulator and nickel-plated steel terminal keep the microamp signal clean and the connection corrosion resistant.
Approved and warranted: CSA approved with a 3-year limited warranty and a YYWW date code on every sensor.

Common Questions

What does the 790-707A1 replace? It is the White-Rodgers direct replacement for Goodman 0130F00010S, the earlier 0130F00010, and the related B1172606, B11726-06 and 20488501 numbers. Match the original sensor number or the furnace model before ordering.
Does the rod need to be bent? No. The 790-707A1 has a straight (180°) rod made for the Goodman position. For a sensor that must be shaped to match another brand, use the universal 790-843A1.
How do I know the flame sensor is bad? Symptoms are a furnace that lights and shuts off within seconds. Read the microamp signal with the flame on. Under about 0.5 µA after cleaning the rod, and with a good ground and solid wiring, points to replacing the 790-707A1.
