Maytag Bravos Check Vent Light Keeps Coming On
« on: December 21, 2016, 07:28:23 AM »
Purchased this dryer two years ago.  Everything worked fine through 8 feet of 4 inch vent duct until October 2016.  Keep getting the check vent light.  To date the following has been done:
1. Control board has been replaced with new.  Check vent light still comes on.
2.  Thermistor has been replaced.  Check vent light still comes on.
3. Replaced vent duct with new/clean ducting.  Check vent light still comes on.
4. Took dryer apart and cleaned of all lint on the inside.  Check vent light still comes on.

How do I enter the diagnostic mode to check inlet airflow?  The service manual I downloaded does not work for my control board.
What could be causing this issue?

Thanks!  Ran the diagnostic and found the following:
L1 Voltage 107 VAC
L2 Voltage 108 VAC
L1 to L2 Voltage 214 VAC
Airflow test gives codes F04 E03 Restricted Airflow

Could the line voltage being just out of tolerance cause this issue? I am now thinking the blower motor does not have voltage for proper airflow and the heater unit does not have enough voltage to properly control temperature.

Problem is fixed.  Found the inlet thermistor to be out of range.  Replaced both the inlet and outlet thermistors.  Also solved the low voltage problem in the earlier diagnostics.

There was no power problem.  The thermistor was also causing problems for the control board diagnostics.
