Goodman Service Limit L220F /-30F

The Goodman 1370914S is a new HVAC control component designed as a service limit switch. It carries the specific temperature ratings L220F and -30F for system protection. The unit features a transparent housing for visual inspection. This part is intended for use in heating and cooling equipment requiring these limit parameters.

Suits technicians replacing a Goodman 1370914S

This component suits HVAC professionals servicing Goodman systems that specify the L220F and -30F ratings. It is not for installers needing a different temperature calibration or a switch with alternate mounting dimensions. Buyers without the equipment documentation to verify the exact part number should look elsewhere.

Rated for L220F high limit and -30F low limit

The switch provides over-temperature protection at the 220F threshold and low-temperature monitoring down to -30F. It handles the safety circuit interruption for these specific set points. The device does not offer adjustable range or additional staging capabilities beyond the stated limits.

Questions about this item

What HVAC system specifications must I already have for the 1370914S Service Limit L220F /-30F to function correctly?

The control is designed as a safety limit for Goodman heating equipment; your furnace or air handler must use a L220F /-30F rated limit switch in its control circuit.

Will the 1370914S Service Limit operate reliably alongside the original control board and wiring in my older Goodman unit?

Yes, it is a direct replacement limit switch built to the same L220F /-30F specification, so it integrates with the existing board and wiring without modification.

How can I verify the 1370914S Service Limit is working as intended after installation?

After power is restored, the furnace should complete a normal heating cycle and the limit must remain closed until the airstream reaches 220 °F, opening only at that temperature.
