Pat K for Model Number Maytag Dryer Model MGDB850WQ0 Electronics aren't working right. Will only set for 3 minutes and sometimes it will run longer. Others don't light up anymore so we can't get the settings to work.
Answer Pat, here's how to enter the diagnostic test mode and check the user interface buttons and display : 1. Be sure the dryer is in standby mode (plugged in with all indicators off, or with only the Clothes Dry indicator on). 2. Select any one button (except Power/Cancel) and follow the steps below, using the same button (remember the button): press/hold 2–5 seconds, Release for 2–5 seconds, Press/hold 2–5 seconds, Release for 2–5 seconds, Press/hold 2–5 seconds 3. If this test mode has been entered successfully, all indicators on the console are illuminated for 5 seconds with 8:88 showing in the Estimated Time Remaining three-digit display. If there are no saved fault codes or active fault codes, all indicators on the console will momentarily turn off, then stay on with 8:88 displayed. Continue with diagnostics. 4. If entry into Diagnostic Test Mode is unsuccessful, choose a different button (except Power/Cancel) and repeat step 2. DIAGNOSTIC: Console Buttons and Indicators Pressing buttons and rotating the cycle selector will turn off the corresponding indicator and sound a beep as shown in figure 1. Pressing Time Adjust (+) will toggle the left digit and colon on the display while sounding a beep.essing Time Adjust (–) will toggle the right two digits on the display and the status indicators while sounding a beep. Pressing the End Signal button will activate the Line Voltage Test. If indicators fail to come on and beep after pressing buttons and rotating the cycle selector. Perform steps in Accessing & Removing the Electronic Assemblies,and visually check that the P5 connector is inserted all the way into the machine control electronics. Visually check that the user interface assembly is properly inserted into the front console. If both visual checks pass, replace the user interface assembly. Plug in dryer or reconnect power.Perform the Console Buttons and Indicators Diagnostic test. If indicators still do not light, the machine control electronics has failed. rotating the cycle selector Pressing the End Signal button will activate the Line Voltage Test.
