1300

Low oil pressure

Engine · Alarm

Gentek's Sync/Evolution guide calls 1300 the normal shutdown for low oil or low oil pressure. It lists three causes: oil level low (the common one during a long outage), a faulty low-oil-pressure switch when the level is actually fine, or an internal problem so the engine is not building oil pressure. It is not the overspeed code. Overspeed in the same guide is 1200.

Seen on: Honeywell Sync 2.0 and 3.0 home standby controllers. Gentek's Evolution fault guide says this e-code list applies to those Sync controllers because they use the Generac Evolution control.

Likely causes

  • Low oil level.
  • Faulty low-oil-pressure switch.
  • Engine not building oil pressure, which the guide says requires a pressure test.

Checks an owner can do

  1. Engine off: check the oil level and fill only to the full mark.
  2. If the level was low, correct it and do not treat a repeat trip as 'just the sensor' without a test.

When to call a pro

The guide says a pressure test is required when the level is correct, and that a bad switch is replaced after that test. Do not bypass the switch.

Source

Gentek Power Generac Evolution 1.0/2.0 fault guide (November 2018), which states the same e-code list applies to Honeywell Sync 2.0/3.0. Meanings below are limited to rows quoted from that guide.

Wording follows that document. Firmware can change a threshold. If this page and the manual shipped with your unit disagree, follow the manual.
