GE Dryer Error Codes — Full Diagnostic Guide

Common Symptoms

• Error code displayed on GE dryer control panel (E1, E2, E3, E4, E5, E6, d5, t5)
• Dryer stops mid-cycle and displays a fault code
• Dryer runs but produces no heat — E1, E2, or t5 displayed
• Dryer will not start — E3 or E4 displayed at power-on
• Door opens mid-cycle and dryer shuts down — E6 or d5 displayed
• Control panel unresponsive or flickering — E5 displayed

Most Likely Causes

1. 1

   E1 — Drum Outlet Thermistor Open or Short

   E1 indicates the drum outlet thermistor (WE4M409) has failed open or shorted. This sensor monitors the temperature of air exiting the drum at the drum-to-exhaust transition. At room temperature (approximately 70°F), a functional WE4M409 reads approximately 10,000Ω (10kΩ). An OL reading on a multimeter indicates an open (broken) thermistor element; near-0Ω indicates a short. The E1 code stops the heat circuit as a safety measure — the dryer may continue tumbling without heat. On GTD65EBSJWS and GTD42EASJWW, the drum outlet thermistor is accessible after removing the rear panel. E1 is the most commonly replaced GE dryer sensor.

2. 2

   E2 — Exhaust Thermistor Fault

   E2 indicates the exhaust duct thermistor (WE4M415) is out of range or has failed. The exhaust thermistor is mounted inside the exhaust duct near the rear of the cabinet and monitors the temperature of air leaving the dryer. Like E1, it is an NTC thermistor — resistance decreases as temperature rises. Spec is approximately 10kΩ at room temperature. E2 may also indicate a wiring harness fault between the sensor and the control board rather than the sensor itself — check the harness connector before condemning the sensor. On GFD65ESSNWW (front-load), accessing the exhaust thermistor requires removing the rear or lower access panel.

3. 3

   E3 — Motor Relay or Motor Overload

   E3 indicates the motor relay on the control board has detected a fault, or the motor's internal thermal overload has tripped due to overheating. Root causes: (1) motor thermal overload — the motor ran hot due to a restricted exhaust duct, overloaded drum, or a failing motor bearing; the overload typically resets after 30 minutes of cooling; (2) failed motor start relay or motor control relay on the board; (3) seized drum — check that the drum rotates freely by hand before condemning the motor. On GE models, the start relay WE4M527 mounted on the motor is a frequent cause of E3-adjacent motor faults. Shake the relay when removed — a rattling relay has a failed contact.

4. 4

   E4 — Heater Relay Stuck On

   E4 indicates the heater relay on the control board has stuck in the closed (on) position, meaning the heating element is energized when it should not be. This is a safety-critical fault — a stuck heater relay can cause the drum to overheat, damaging clothing or posing a fire risk. The dryer shuts down to prevent overheating. The root cause is almost always a welded relay contact on the main control board (WE4M527 board). Before condemning the board, confirm the fault by disconnecting the heater leads and checking whether the E4 code clears — if it does, the relay is the board fault. Do not restart the dryer with E4 active until the control board is replaced.

5. 5

   E5 — User Interface Board Communication Fault

   E5 indicates a communication failure between the main control board and the user interface (UI) board — the control panel assembly with buttons and display. Causes include a loose or damaged ribbon cable connecting the two boards, moisture inside the control console, or a failed UI board or main board. Start diagnosis with a hard reset (unplug for 5 minutes). If E5 persists, inspect the ribbon cable connection at both ends — reseat firmly. If E5 returns after reseating, test by temporarily connecting a known-good UI board if one is available. UI board replacement (WE4M527 family) typically resolves persistent E5.

6. 6

   E6 / d5 — Door Switch Fault

   E6 indicates the door switch opened unexpectedly during a cycle (the dryer detected the door had opened while running). d5 is the door switch fault code on newer GE models (GTD72EBSNWW, GFD65ESSNWW) and indicates the door switch is not making proper contact at cycle start or during operation. The door switch (WE4M321) is a single-pole switch mounted at the door opening inside the cabinet. Test procedure: with the dryer unplugged, use a multimeter in continuity mode — door closed should show continuity, door open should show open. A switch that reads open with the door fully latched is failed. Inspect the door latch tab on the door itself for cracks or wear that prevent full engagement.

7. 7

   t5 — Temperature Runaway (Safety Shutdown)

   t5 indicates the dryer's control board has detected that drum temperature is rising faster than expected or is not being controlled by the heating circuit — a temperature runaway condition. This is a safety-critical fault. Root causes: (1) failed cycling thermostat allowing the heater to run continuously; (2) heater relay stuck closed (overlaps with E4 — t5 may precede E4 on some models); (3) severely blocked exhaust duct causing rapid temperature buildup; (4) failed thermistor reporting incorrect (low) temperatures that keep the heater energized. Do not restart the dryer with t5 active. Inspect and clean the full exhaust duct first. Then test the cycling thermostat (continuity at room temperature = functional, OL = failed) and the thermistors (WE4M409, WE4M415) before restarting.

Quick DIY Checks

1. 1Enter GE dryer diagnostic/service mode to confirm the active fault code: on most GTD and GFD models, press the Power button to turn the dryer on, then press and hold the Start button for 5 seconds. The display will enter service mode and show the stored fault code. Note: on GTD65EBSJWS specifically, refer to the GTD65 service sheet for the exact button sequence — some GTD65 variants use a different multi-button entry. Some older GE dryer models (pre-2015 GTD series) use a rotary selector sequence rather than a Start-hold. If service mode is not available on your model, the error code displayed at the time of shutdown is the active fault.
2. 2Test drum outlet thermistor WE4M409 (E1 code): unplug the dryer. Remove the rear panel (typically 6–8 Phillips screws). Locate the drum outlet thermistor at the rear of the drum housing where air exits into the exhaust duct — it is a small cylindrical or flat sensor with two wires. Disconnect the sensor harness connector. Set a multimeter to resistance (Ω) mode. Probe both thermistor terminals. At room temperature (65–75°F), a functional WE4M409 reads approximately 10,000Ω (10kΩ). OL = open (failed, replace). Near 0Ω = short (failed, replace). Values significantly higher or lower than 10kΩ at room temperature also indicate a degraded sensor. Reconnect or replace, then retest.
3. 3Test exhaust thermistor WE4M415 (E2 code): same procedure as the drum outlet thermistor (WE4M409). The exhaust thermistor WE4M415 is mounted on or adjacent to the exhaust duct inside the cabinet. Both WE4M409 and WE4M415 have the same resistance spec (~10kΩ at room temperature). It is practical to replace both at the same time when one fails, as they are inexpensive ($10–$20 each) and share a failure pattern.

1. 4Test heating element WE11M23 (for E4/t5 heat-related codes — electric models): unplug the dryer. Remove the rear panel. The heating element WE11M23 is a 240V dual-coil element — it has two separate coils in one housing, each rated approximately 13Ω. Set the multimeter to resistance mode. Measure each coil individually by probing the two terminal pairs. A functional coil reads approximately 13Ω. OL (infinite) on either coil = open coil, element must be replaced. Also check for continuity between each coil terminal and the element housing (ground) — any continuity to ground indicates a shorted element that could trip the breaker.
2. 5Test door switch WE4M321 (E6 / d5 codes): unplug the dryer. Open the dryer door. Locate the door switch inside the front cabinet opening — typically mounted on the door frame or front bulkhead, accessible after removing the front panel on most GTD/GFD models. Disconnect the switch wires. Set multimeter to continuity mode. With the switch plunger RELEASED (door-open position): should read open (no continuity). Press the plunger in (simulating door closed): should read continuity. A switch that reads open with plunger pressed = failed, replace WE4M321. Also inspect the door latch strike (the plastic tab on the door that presses the switch plunger) for cracks, missing material, or excessive wear.
3. 6Test motor start capacitor WE1M652 (E3 / motor fault): unplug the dryer. The motor start capacitor WE1M652 is mounted near the motor inside the cabinet (access from front or rear depending on model). WARNING: capacitors store charge — discharge the capacitor before probing by placing a 10kΩ resistor across its terminals for 30 seconds, or use an insulated screwdriver to briefly short the terminals. Set multimeter to capacitance mode (µF). A functional WE1M652 reads within 10% of its rated capacitance (check the label on the capacitor). A reading of 0 µF, OL, or significantly out of spec = failed capacitor. Replacement restores motor start torque and typically clears E3 caused by motor thermal overload.
4. 7Test gas igniter WE14M37 (gas models — E3 or no-heat with no error code): unplug the dryer and close the gas supply valve. Remove the lower access panel to expose the burner assembly. Disconnect the igniter wires. Set multimeter to resistance mode. A functional hot-surface igniter WE14M37 reads approximately 50–500Ω (igniters vary; any reading in this range with a glow test confirms function). OL = open igniter, must replace. Gas igniters are fragile — do not touch the ceramic glow element with bare hands; skin oils degrade the element. After replacing, restore gas supply, turn on the dryer, and observe through the burner inspection port to confirm ignition within 60–90 seconds.
