Goodman GMVC960803BN Error Code EE2: Low Stage Pressure Switch Open

What Does Code EE2 Mean?

Error code EE2 on the Goodman GMVC960803BN means the induced draft blower started but the low-stage pressure switch never closed to confirm proper draft. Without that confirmation the integrated control module will not open the gas valve, so the inducer keeps running continuously while the burners stay off. This is the most commonly seen of the four pressure switch codes on this furnace.

On this two-stage, variable-speed 96% AFUE furnace the low-stage pressure switch closes only when the inducer pulls a strong enough negative draft through the flue at the low firing rate. EE2 is the direct opposite of EE1: where EE1 faults the same switch for being stuck closed before the cycle, EE2 faults it for failing to close after the inducer runs. It is also the low-stage equivalent of EE9, the won't-close fault on the high-stage switch — but because it is the low-stage switch, EE2 stops the furnace entirely rather than merely limiting it to low heat.

The causes cluster around anything that starves the switch of draft. Most common are a blocked, kinked, or misconnected pressure switch hose, a blocked flue or inlet-air pipe (ice, snow, leaves, or a nest at the outdoor termination), and a clogged condensate drain that backs water up into the collector box. A weak or failing induced draft blower, a switch with the wrong set point or bad contacts, and loose or corroded wiring can produce the same result.

What You'll Notice

• The induced draft blower runs and keeps running, but the burners never light
• The 7-segment diagnostic display reads EE2
• There is no heat at all despite the thermostat calling for heat
• You may see or hear water backed up around the drain, or ice on the outdoor vent pipe
• The condition often appears after a storm, a very cold snap, or a long-neglected filter/drain

Common Causes

How This Is Diagnosed

A technician starts at the venting side because it is the most common cause: they inspect the pressure switch hose for kinks, cracks, water, or a loose fit, then check the flue and intake terminations outdoors for blockage and verify the condensate drain and trap are clear. Any restriction that reduces draft is corrected first.

If the venting path is clear, the technician measures the actual draft pressure at the switch with a manometer while the inducer runs and compares it to the switch's rated set point. That isolates whether the inducer is too weak to make draft or whether the switch (or its wiring) is failing to close under adequate pressure, and the failed component is replaced.

When to Call a Professional

This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:

• The inducer runs continuously but the furnace never lights and shows EE2
• EE2 remains after the hose, flue, intake, and condensate drain have all been checked and cleared
• The induced draft blower sounds weak, unusually loud, or does not spin up normally
• Water keeps backing up into the inducer or collector box after the drain is cleared
• The switch will not close even though the vent system is confirmed clear
