American Dryer Error Code MODEL ERROR, ENTER CORRECT MODEL

What does American Dryer (ADC) MODEL ERROR mean?

The Phase 7 control is the same family of board across several American Dryer models, so it must be told which dryer it is running. That model setting decides the heat levels, timing and safeties the control applies. If the stored model does not match what the control expects, it refuses to run rather than apply the wrong rules, and it shows MODEL ERROR, ENTER CORRECT MODEL. This usually follows a control replacement, where a new board arrives without the right model, or a memory problem that scrambled the stored value. The manual lists the model setting in the control, a recent control replacement, control memory, and the dryer data plate model. The data plate matters because it is the reference the correct setting is checked against. Operators see a dryer that powers up, shows the message and does nothing else. Nothing in the message points to heat, gas or wiring, so cleaning and restarting do not help beyond one power cycle.

Affected models and control systems

This applies to American Dryer tumblers with the Phase 7 OPL microprocessor controller, such as the AD-115, AD-120 and AD-170, and the Phase 6 control on ML-175 and ML-190 models. Other controller generations use different messages.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• MODEL ERROR, ENTER CORRECT MODEL shows right after power-up
• The dryer will not start any cycle
• The message appeared after a new control board was fitted
• It appeared after a power interruption

Possible causes

Listed in American Dryer (ADC)'s documentation

• Wrong model stored in the control
• A recently replaced control carrying the wrong model
• Control memory has lost or scrambled the model setting
• Stored model does not match the dryer data plate

Other likely causes — what usually sits behind MODEL ERROR on this control. A technician confirms which one it is before any part is replaced.

• A replacement control board delivered without the model for this specific tumbler stored in it
• A power interruption during a settings change that wrote the wrong model value
• A controller swapped from another dryer in the same room with a different model setting

Safe checks before calling for service

How a technician diagnoses MODEL ERROR

1. Read the message and record the model on the data plate.
2. Read the model stored in the control.
3. Set the model to match the data plate, following the manual.
4. Check that the heat and timing values the model selection affects are right.
5. If the model will not hold, check control memory and replace the board.
6. Run a full cycle to confirm heat and timing are right.
