How connect wires at board - Maytag MER5770 Electric Kitchen Range

It is possible that the connections on the circuit board for the bakery car have been installed in the wrong orientation, causing the display to be on the wrong side of the train. If the wiring harness is set up with the male connector on one end and the female connector on the other, reversing the connections on the circuit board would likely correct the issue. However, it is also possible that the problem is with the wiring harness itself and not the circuit board. It's best to check with the manufacturer of the train or circuit board to see if they have a corrected circuit board with reversed connections or if there are any other recommended fixes for this issue.

Hi,

if you want to connect a wire to a circuit board, you'd need to use a soldering iron to attach the wire to the board. Please research using that soldering iron online before proceeding.

Thank you.

Need more info. If you have a heat pump outside you should have a wire landed on O. What was the external board and what was old tstat. Also is this electric heat or gas inside at furnace? Model numbers of equipment will help, where the wires are landed outside also.

Did you find a wire that has become disconnected from the board and is loose inside the TV or did you see a empty connector with nothing connected to it? If you find a wire that has become disconnected and it is nearby the board simply reconnect it. If you're worried about a connector with nothing connected and there is no obvious loose wires near it, you are looking at the test connector TV repair technicians use to trouble shoot the board with. This ia normal.

if theres a wire from the center terminal on the dryer terminal board going to the dryer case disconnect it,then Red & Black on the cord go to the outer 2 terminals on the dryer terminal board,the White goes to the terminal in the center between where you put the Red & Black wires this is the Neutral wire,then the Green wire connects to any metallic portion on the dryer case as this is the SAFETY Ground wire and also Red & Black can go on either outer terminal on the dryer terminal board as these are not polarity sensitive because its A.C. power so wire it on the dryer terminal board as in (RED-WHITE-BLACK) on the dryer terminal strip and connect the GREEN to any Metallic portion of the dryer case

I suggest unplugging the dryer and checking the wiring connection of the thermistor to the electronic control board. The thermistor attaches to the control board on the P2 connector (red/white and black wires on pins 5 and 6).

The image below shows the procedure for accessing the control board in this dryer (click image for zoom). If the connection is okay, pull the connector off of the control board and check the resistance through the red/white wire and black wire with a volt/ohm meter (with the dryer still unplugged). You should measure about 10K ohms (10,000 ohms) at room temperature. Make sure that your meter is set to the proper range. If you read infinite resistance (open), then you could have a wire harness connection problem between the control board and the thermistor. Check the resistance across the leads of the thermistor (with at least one wire removed from the thermistor). If you measure normal resistance (10K ohms) at the thermistor, then you will need to repair the wiring connection between the control board and the thermistor.
If you measure the proper resistance through the thermistor circuit at the connection to the control board (red/white wire to black wire on the P2 connector), then the electronic control board is bad and will need to be replaced.



Hope helps.

your thermostat powers 'Y' for cooling. That in your case blue wire connects to 'Y' on the control board in the furnace. Then a pair of low-voltage wires connects 'Y' and 'C' on the furnace to the two wires to the coil of the contactor in the a/c condensing unit. So to follow the path, the signal wire from the thermostat sends 24v down the Y wire to the furnace board Y terminal which also connects to one side of the contactor coil in the air conditioner. To complete the control circuit to the air conditioner there has to be a common wire. This is connecting the C wire from the furnace board to the other side of the contactor in the air conditioner. Hope this helps.

The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.

This may be somewhat difficult depending on the year make and model. I will try to help without this knowledge.

There are 2 sides to the transformer. Read the label to see which is which. One side is labeled 24 volt and the other side is labeled 115 volt.

The 115v side will probably only have 2 wires. A white wire and a black wire. The white one will connect to the common or neutral system. If there is a circuit board it will plug on to the 120v Common terminal (probably marked L2). If the air handler does not have a circuit board, the white wire will connect to the other white common wires by a wire nut.

The Black (hot) 120v wire will connect to the 120v L1 terminal on the circuit board. If there is not a circuit board, read the schematics to find out where to wire nut the black 120v wire to. It will obviously be connected to a 120v incoming hot center after the blower door switch.

The 24volt wires will connect in a similar fashion to the circuit board. T1 will connect to the 24v hot terminal on the board. The T2 will connect to the 24v common terminal. If there is not a circuit board you will need to read the schematics very carefully before proceeding. It may be a good idea to add a 2amp fuseable link on the 24v T1 wire just in the case we are wrong.

The 24v hot wire may be wired in multiple ways without a circuit board. One way is to be wired to the Limit side of the Fan/Limit switch (located on back wall of the burner compartment just above the gas valve. Another way is wired to the gas valve. Please read the schematics located on the blower door. I hope this helps at least a little. Let me know please. Thanks.
