Maytag codesMaytag dryer codes

High limit exceeded; temperature threshold of the dryer has been exceeded, usually indicating poor airflow caused by exhaust restriction or blower wheel failure.

First step from the service manual

What F4E5 means on a Maytag dryer

The F4E5 error code on a Maytag dryer indicates that the high limit temperature threshold has been exceeded. This code is triggered when the control board detects temperatures inside the dryer drum or exhaust pathway that surpass safe operating limits. The high limit thermostat or thermal limiter acts as a safety cutoff, and when temperatures climb beyond design parameters, the system flags this fault to prevent damage to internal components and reduce fire risk.

The most common root cause is restricted airflow through the exhaust system. When hot, moist air cannot exit the dryer efficiently, heat builds up inside the drum and surrounding components. Lint blockages in the exhaust duct, a crushed or kinked vent hose, or a clogged exterior vent cap are frequent culprits. A failed blower wheel, whether broken, clogged with debris, or seized, will also prevent adequate airflow and produce the same result.

In some cases, the high limit thermostat itself may have failed in a way that causes it to trip prematurely, even when airflow is adequate. Additionally, a faulty heating element that remains continuously energized can generate excessive heat independent of airflow conditions. Diagnosing F4E5 requires a systematic check of the full exhaust pathway first, followed by inspection of the blower wheel and heating components if the venting system is found to be clear.

Common causes of F4E5

  1. 01

    Clogged or restricted exhaust duct

    Wiring / connection

    Lint buildup inside the exhaust duct, a kinked flexible vent hose, or a blocked exterior vent cap prevents hot air from escaping. Disconnect the duct and check the full length for obstructions.

  2. 02

    Failed or obstructed blower wheel

    Part replacement

    The blower wheel pulls air through the drum and pushes it out the exhaust. A broken blade, a wheel clogged with lint, or a seized bearing will drastically reduce airflow and cause heat to build up. Inspect the blower wheel for damage or debris after removing the dryer cabinet.

  3. 03

    Tripped or failed high limit thermostat

    Part replacement

    The high limit thermostat can fail open or trip permanently after an overheating event. If the vent system checks out clean, test the thermostat for continuity and replace it if it has lost continuity.

  4. 04

    Faulty heating element

    Part replacement

    A heating element that shorts to its housing can remain energized continuously, generating heat even when the control board is not calling for it. This produces excess heat regardless of airflow conditions.

  5. 05

    Clogged lint screen housing

    Wiring / connection

    Lint can bypass the screen and accumulate in the lint trap housing or the internal ducting leading to the blower. Clean the lint screen housing thoroughly and check the internal duct passage for buildup.

Frequently asked questions about F4E5

What does F4E5 mean on a Maytag dryer?
F4E5 means the dryer has exceeded its high limit temperature threshold. The dryer's control board detected unsafe heat levels, which is most often caused by restricted exhaust airflow or a failure of the blower wheel. The code is a safety response designed to stop operation before damage or a fire hazard can occur.
How do I fix the F4E5 error on my Maytag dryer?
Start by inspecting the full exhaust duct from the back of the dryer to the exterior vent cap, clearing any lint or obstructions. Clean the lint screen and its housing thoroughly. If the venting is clear, inspect the blower wheel inside the dryer for damage or debris. If the blower wheel is intact, test the high limit thermostat for continuity and check the heating element for shorts.
Is the F4E5 error on a Maytag dryer a safety concern?
Yes, this error should be taken seriously. Excessive heat inside a dryer is a recognized fire hazard, particularly when lint is present in a restricted duct. Do not continue to operate the dryer until the cause of the overheating has been identified and corrected.
Will resetting my Maytag dryer clear the F4E5 error code?
Unplugging the dryer and restoring power may temporarily clear the code, but it will return if the underlying problem has not been fixed. The fault condition that caused the overheating must be resolved, whether that is a blocked vent, a failed blower wheel, or a faulty thermostat, before the dryer will operate reliably.
How much does it cost to repair a Maytag dryer showing F4E5?
Repair costs vary depending on the cause. If the issue is simply a clogged exhaust duct, costs are minimal and may only involve your time or a professional duct cleaning service ranging from $75 to $150. Replacing a high limit thermostat or blower wheel typically involves part costs in the $15 to $80 range plus labor if a technician is hired, with total repair bills often falling between $100 and $250 depending on your location and the specific parts needed.
