Goodman Furnace E5 Error Code: Pressure Switch Error

Quick Answer

Goodman E5 is the general pressure switch error code. Unlike F02 (switch stuck closed before start) or 9H (high pressure switch opened during operation), E5 covers a broader set of pressure switch circuit faults including open circuits, short circuits, and failed transitions. The condensate drain is still the first thing to check because drain blockage affects pressure readings directly.

Goodman E5 is the general pressure switch error code. Unlike F02 (switch stuck closed before start) or 9H (high pressure switch opened during operation), E5 covers a broader set of pressure switch circuit faults including open circuits, short circuits, and failed transitions. The condensate drain is still the first thing to check because drain blockage affects pressure readings directly. After that, inspect the hose routing and test the switch for proper open/close behavior with a multimeter. A failed pressure switch on a GMVC96 or GMSS92 typically costs $20-45 and takes under 30 minutes to replace.

What Does the E5 Code Mean?

E5 is the catch-all pressure switch fault. Check the condensate drain first, then the hose, then test the switch itself with a multimeter. It covers issues that F02 and 9H do not specifically classify.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Condensate drain clog affecting pressure switch readings40%
Pressure switch failed open or with incorrect trip point24%
Induced draft motor not producing adequate pressure22%
Hose kinked, disconnected, or filled with condensate14%

Symptoms You May Notice

  • Furnace not completing startup sequence
  • LED flashing E5 on control board
  • Inducer runs but ignition does not start
  • Furnace cycling without reaching ignition stage

Can you reset a Goodman furnace to clear the E5 code?

After clearing the drain, fixing the hose, or replacing the pressure switch, flip the circuit breaker off for 30 seconds, then restore power and call for heat. If E5 returns, verify the condensate drain is fully clear and the hose is routed without any low-hanging sections that could trap water.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Locate the condensate drain trap and drain outlet

Locate the condensate drain trap and drain outlet. Use a wet/dry vac at the drain outlet for 30 seconds, then pour a cup of warm water into the condensate trap. Verify water flows freely through the drain.

2

Trace the pressure switch hose from the inducer housing to the switch

3

Test the pressure switch with a multimeter set to continuity

4

If drain, hose, and switch all test correctly, observe the

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

How is E5 different from F02 and 9H on a Goodman furnace?
F02 specifically means the pressure switch is stuck closed before the inducer starts. 9H means the high-stage pressure switch opened during operation. E5 is a more general pressure switch circuit fault that does not fit the specific timing of F02 or 9H - it covers open circuits, short circuits, and failed transitions at other points in the startup sequence.
Can I test a pressure switch without special tools?
Yes. Disconnect the hose from the switch port. Set a multimeter to continuity. With no vacuum applied, the normally-open switch should show no continuity. Apply gentle suction by mouth at the port and the switch should click and show continuity. Release and it should open again. This basic test confirms switch function without a gauge.
Does E5 mean my furnace is dangerous to run?
E5 itself prevents ignition, so the furnace is not running at all. The pressure switch is a venting safety device - when the furnace is in E5, it is being cautious rather than dangerous. However, do not bypass the switch to force ignition. Fix the root cause and let the switch operate as designed.
