Maytag Dryer Error Code Coin 1

Coin 1 failure. For PN models

Maytag codesMaytag dryer codes

Coin 1 failure. For PN models: make sure cycle price is set to zero and coin option is not selected (set-up mode 6 should be set to 00 for free cycle operation; set-up mode J. should be set to _d to prevent coin drop diagnostic codes).

First step from the service manual

Ensure set-up mode 6 is set to 00 and set-up mode J. is set to _d (PN models).

What Coin 1 means on a Maytag dryer

The Coin 1 error code on a Maytag dryer indicates a failure condition related to the coin acceptance or coin drop system. This code is specifically relevant to PN model variants, which are configured for coin-operated or vended laundry operation. The dryer's control board monitors coin input signals during operation, and when it detects an unexpected coin-related signal or a conflict in the configuration settings, it registers the Coin 1 fault. This prevents the machine from operating incorrectly in environments where it should be running as a free-cycle unit rather than a pay-per-use appliance.

The root cause of this error is almost always a configuration mismatch in the dryer's set-up mode parameters rather than a hardware component failure. Set-up mode 6 controls the cycle price setting, and it must be programmed to 00 for free-cycle operation. Set-up mode J. controls coin drop diagnostic behavior, and it must be set to _d to suppress coin drop diagnostic codes. If either of these parameters is set incorrectly, the control board interprets the machine as expecting coin input, and when that input is absent or inconsistent, the Coin 1 fault is generated.

In rare cases where the configuration settings are already correct and the error persists, the issue may point to a wiring problem or a fault in the coin acceptor assembly itself, such as a stuck coin switch or a shorted input signal line reaching the control board. However, the configuration check must always be completed first, as it resolves the vast majority of Coin 1 faults on PN model dryers.

Common causes of Coin 1

  1. 01

    Incorrect cycle price setting (Set-up mode 6)

    Wiring / connection

    Set-up mode 6 is not set to 00, which means the control board believes a coin payment is required for each cycle. This is the most frequent cause of the Coin 1 error on PN models being used for free-cycle operation.

  2. 02

    Coin drop diagnostic mode not disabled (Set-up mode J.)

    Wiring / connection

    Set-up mode J. is not configured to _d, so the control board actively monitors for coin drop events and generates a diagnostic fault when no coin signal is received. Setting J. to _d disables this monitoring.

  3. 03

    Both set-up modes misconfigured simultaneously

    Wiring / connection

    In some cases, both set-up mode 6 and set-up mode J. are set incorrectly at the same time, compounding the fault. Both parameters must be corrected together to clear the error.

  4. 04

    Shorted or faulty coin acceptor wiring

    Wiring / connection

    If configuration settings are correct and the fault persists, a wiring issue between the coin acceptor assembly and the control board may be sending a false coin signal. Inspect the wiring harness for pinched, shorted, or damaged wires.

  5. 05

    Defective coin acceptor assembly

    Part replacement

    A stuck or failed coin switch within the coin acceptor can generate a continuous or erratic input signal to the control board, triggering the Coin 1 fault even when configuration is correct. Replacement of the coin acceptor assembly would be required.

Frequently asked questions about Coin 1

What does Coin 1 mean on a Maytag dryer?
The Coin 1 error code indicates a failure in the coin acceptance or coin drop system on PN model Maytag dryers. It typically means the dryer's internal configuration settings do not match its intended operation mode. Specifically, the cycle price setting or the coin drop diagnostic setting is programmed incorrectly, causing the control board to flag a fault. In most cases, correcting set-up mode 6 and set-up mode J. resolves the error without any parts replacement.
How do I fix the Coin 1 error on my Maytag dryer?
Start by accessing the dryer's set-up mode and verifying that set-up mode 6 is set to 00, which programs the unit for free-cycle operation with no coin price requirement. Next, confirm that set-up mode J. is set to _d, which disables the coin drop diagnostic code function. If both settings are already correct and the error persists, inspect the wiring connected to the coin acceptor assembly for damage, and consider replacing the coin acceptor if no wiring fault is found.
Is it safe to use my Maytag dryer while the Coin 1 error is displayed?
The Coin 1 error is a configuration or coin system fault, not a heating or mechanical safety issue, so it does not present a direct safety hazard. However, the dryer may refuse to start or complete cycles properly while the fault is active. It is best to resolve the configuration settings before relying on the appliance for regular use.
Will resetting my Maytag dryer clear the Coin 1 error code?
A simple power reset by unplugging the dryer will not permanently clear the Coin 1 error if the underlying configuration settings remain incorrect. The fault will return as soon as the dryer powers back on because the control board will continue to detect the misconfigured coin settings. The error will only clear after set-up mode 6 is set to 00 and set-up mode J. is set to _d.
How much does it cost to repair a Coin 1 error on a Maytag dryer?
If the error is caused by incorrect set-up mode configuration, the repair costs nothing beyond the time needed to access and adjust the settings. If a technician is called to perform the configuration adjustment, expect a service call fee in the range of $75 to $150 depending on your location. In the less common scenario where a coin acceptor assembly needs replacement, parts and labor combined could range from $100 to $250.
