Getting code 93,both controller boards replaced, new installation

possible causes include
excessive gas
low gas
relay not working,
faulty thermostat
faulty start/run capacitor
bad circuit board

probably not
it could be in the way you connected the new board or that was not the fault to start with
thermostats just control the temperature to within set parameters

Hello Wendi & Mike;

My name is Peter. I am a retired field service appliance technician.

If these guys in the parts store should not tell you what the problem is, otherwise they would be in the field repairing the appliances and making good money.

I am sorry you have gone through so much unnecessary expense.

You have not provided a model number which would help me solve the problem.

Anyway, The "AF" code either means Air Flow or Air Fan.

1.) Air fan:
a.) Open the dryer door. Try to rotate the dryer drum by hand. Does it move freely?
b.) With the door open. Hold the door switch in, turn on the dryer, does the drum turn? If so then your motor and fan wheel are good. Your fan wheel may be stuck with lint.

2.) Plugged up with lint:
You have a hot air distribution manifold. This often becomes plugged up especially if you have children or pets. In this case you may smell a burning odor.

3.) High temperature thermal switch and operating switch. These components are on your electric heater housing. Disconnect the wire contacts on these components. Note the color of the wires and where they go. If the two wire are the same color then it makes no difference when you reconnect them. Set your meter on Ohms for tone ring. Check these components.

Go into the following website. Put in your model number. You will get diagrams and part numbers for your dryer components. Purchase them over the internet for about 40-50% less.searspartsdirect.com

If after checking all of the above, then you have a control board problem. Don't panic! Take the control board part number on the website and search the internet. Sears wanted $265.00 for a control board. I purchase a used/remanufactured board over the internet for $40.00.

IF YOU DETERMINE IT IS THE CONTROL BOARD, GROUND YOURSELF BY TOUCHING BARE METAL BEFORE YOU TOUCH THE CONTROL BOARD. STATIC ELECTRICY WILL KNOCK OUT A CONTROL BOARD.

Stove will not turn off CHECK

Temperature Control Thermostat

If the oven won't turn off the oven thermostat is often the cause of the problem. The electrical contacts inside the oven thermostat can weld themselves together and then the oven won't turn off. If this happens, turn off power to the entire appliance at the household circuit breaker or fuse. The oven thermostat usually cannot be tested and must be replaced if defective.

Oven Control Board

The oven control board has a set of relays that turn on and off power to the bake and broil circuits according to the customer settings and sensor input. If the oven won't turn off it could be that one of the relays on the oven control board is shorted closed, providing voltage to the heating circuit. It can be dangerous if the oven won't turn off. Don't leave the oven unattended without turning off power to the oven.

Relay board:
Some ovens are equipped with a relay board. This circuit board has several relays which control the switching of electrical current to the oven heat source. If the oven won't turn off it may be that one or more of the relays on the relay board have failed. If this happens replace the relay board. The relays on the board are not sold separately. ALSO CHECK THE BAKE AND BROIL ELEMENT.

: I offer free advice bcuz God is so good!

The main control board thinks the door switch circuit is "open" - you would need a professional to . Is the loading door closed? No, close the door. Yes, go to step (2). 2. Disconnect the plug from J2 on the Main Control Board and check for continuity between the pins in the plug. Open, check the door strike. If good, replace the door switch assembly. Closed, replace the Main Control Board.

Hi.

Check the operations of the High limit Thermostat
The thermostat is installed in line between control board and element. If water is cold read impedance at thermostat's terminal. A good high limit switch must read a couple of Ohms or zero. If it reads infinity then the thermostat must be replaced. If the thermostat returns low impedance it may still be defective opening too soon.
If replacing the thermostat does not do the job, check pressure switch operation (that determines water level) and control board.

Here all parts and diagrams for your model.

Regards.

check the thermostat and replace if needed.if you have an electronic control board this will also cause the temp not to risie properly.also make sure there is no restrictions with the gas flow.

Once you have installed the jumper, you will need to kill power to the furnace for about a minute to reset the board. Make sure the the jumper is making good contact. Sometimes they appear to be plugged in but still are not making contact.

You have a problem with the defrost cycle. Your evaporator in the freezer is getting icedup and blocking airflow. I don't know your exact model but if it has a defrost timer then replace that and the defrost bimetal thermostat in the freezer. They are both cheap and easy to install. If your refrig has a control board then you will need to buy a new board because the defrost is controlled by the board. The boards are not cheap though.

Ok, test the element for its operational value. if the element is not getting a signal to warm from the control board, this will be the issue, considering that the element is new and able to warm. replace the Oven control in this case.

JUst to be safe, back track the installation to make sure every connection was properly united. make sure the element was installed correctly. if so, replace the control.
