0130F00036 – AUTO LIMIT SWITCH (MICRO, LARGE BASE, L180°)

Automatic-reset temperature limit switch for Goodman/Amana furnaces, recorded as a micro-style switch on a large base with an L180 degree F opening point. It opens the control circuit if heat-exchanger or plenum temperature exceeds the set point and closes again on its own once the temperature falls back into range. Limit switches are not interchangeable by appearance – the base style and the L-number must both match. Goodman/Daikin publishes no public part detail, so the specifications below come from our own stock records; confirm against the part nameplate before installing.

Before you order

Coverage spans both 80% AFUE (ACEC / ACES / GCES / GDH80 / GDH81) and 92–97% AFUE (GMSS92 / DR92SN / DM97MC) furnaces. Because the published list runs to 937 models, treat the above as examples, not limits — look your own model up before ordering. Always match the full model and serial number on your unit before ordering.

What does L200-40 mean on a furnace limit switch?

L is limit, 200 is the temperature in F where the contacts open on a rise, and 40 is the differential, so it closes back around 160F. That is an auto-reset disc. Manual-reset limits have a button and stay open until somebody pushes it. Bring the old one in so we can match the temperature, the mounting hole pattern, and the probe length together.

My limit keeps tripping. Is the switch bad?

Usually not. A limit is a safety reading real heat, and most repeat trips we hear about trace back to airflow - a loaded filter, closed or blocked registers, an undersized return, a dirty blower wheel, or a plugged evaporator coil sitting above the heat exchanger. Check temperature rise against the nameplate range, often 40-70F or 45-75F. Rise above the top number means airflow, not a bad switch.

Can I use a hotter limit if that is what is in stock?

No. L200, L230, L250 and L290 differ only by trip temperature and by base or probe size, and they are not interchangeable. Dropping a hotter limit into a furnace that specced a cooler one lets the heat exchanger run past the temperature it was tested to. That is defeating the safety, not fixing it.

Does insertion length matter?

Yes. A 3 inch probe where 5 inch was called for sits in the wrong part of the airstream, reads low, and trips late or never. Measure the old probe from the back of the mounting plate to the tip.
