Maytag Range vent hood touchpad doesn't work: Common Causes & How to Fix

Repair Instructions:

If testing shows the thermal fuse has continuity and the touchpad control is getting electricity, then the touchpad is probably broken and needs replacing. Use a multimeter to check the thermal fuse for continuity. Also verify with a multimeter that power is reaching the touchpad when turned on. If those check out okay but the touchpad still does not work right, it will need to be swapped out. Get a replacement touchpad made specifically for your appliance model. Follow the wiring diagram carefully to connect all the wires when installing the new touchpad. This should restore proper function if the original touchpad was faulty.

How to Replace Range Vent Hood Touchpad

1. Turn off power and disconnect electrical supply - Locate the circuit breaker for the vent hood and turn it off. Disconnect any wiring connectors.

2. Remove mounting screws - Remove the small screws that secure the touchpad to the vent hood.
3. Detach touchpad - Gently pry off the old touchpad from the vent hood. Take care not to bend or damage it.
4. Disconnect wiring - At the rear, disconnect any wiring connectors attached to the touchpad.
5. Attach wiring to new touchpad - Connect the wiring to the terminals on the back of the new replacement touchpad.
6. Position new touchpad - Place the new touchpad into position on the vent hood, aligning any screw holes.
7. Secure with mounting screws - Insert and tighten the small mounting screws to secure the new touchpad.
8. Restore power - Restore power to the vent hood.
9. Test operation - Turn on the vent hood and test that the new touchpad powers on and activates fan speeds properly.
10. Reassemble vent hood - Replace any other components or covers that were removed during the repair.

Repair Instructions:

The control board that operates the user display might be broken. But these boards are often thought to be bad when they actually work fine. Before replacing the user control and display board, first check the other parts that more often go wrong. Things like switches, sensors, wires and fuses should be tested first when there is a problem. That's because those cheaper parts fail most of the time, not the control board. Only replace the board if testing proves the switches, sensors, wires and fuses are okay. Jumping to replace the control board is expensive if it's not really faulty.

How to Replace Range Vent Hood User Control and Display Board

1. Turn off power and disconnect electrical supply - Locate the circuit breaker for the vent hood and turn it off. Disconnect all wiring to the control board.

2. Remove access panel - Remove any access panels from the vent hood to access the control board.
3. Detach all wiring connectors - Disconnect all wiring harness connectors attached to the control board.
4. Remove mounting screws - Remove any mounting screws securing the control board in place.
5. Remove old control board - Carefully maneuver the old control board out of the vent hood.
6. Install new control board - Align and insert the new replacement control board into proper position.
7. Replace mounting screws - Reinsert and tighten mounting screws to secure the new control board.
8. Reconnect wiring harnesses - Reattach all wiring harness connectors to the correct pins on the new control board.
9. Replace access panel - Replace any access panels that were removed from the vent hood.
10. Restore power and test - Restore power and test that the new control board functions properly.

Repair Instructions:

The main control board that operates everything could be broken. But these boards are often assumed bad when they actually still work. Before replacing the main control board, first check the other parts that fail more often. Things like switches, sensors, wires and fuses should be tested first if there's an issue. That's because those cheaper parts usually go wrong more than the control board. Only replace the board if testing shows the switches, sensors, wires and fuses are fine. Jumping to replace the control board is pricey if it's not really faulty.

How to Replace Range Vent Hood Main Control Board

1. Turn off power and disconnect electrical supply - Locate the circuit breaker for the vent hood and turn it off. Disconnect any wiring connectors.

2. Remove filters and baffles - Remove any filters, baffles or covers obstructing access to the main control board.
3. Detach wiring connectors - Disconnect all wiring harnesses and connectors attached to the main control board terminals.
4. Remove mounting screws - Remove the mounting screws securing the main control board to the vent hood.
5. Remove main control board - Carefully remove the old main control board from the vent hood chassis.
6. Install new main control board - Place the new main control board into position, aligning any mounting holes.
7. Replace mounting screws - Insert and tighten screws to secure the new main control board.
8. Reconnect wiring - Reattach all wiring connectors to the terminals on the new main control board.
9. Replace filters and baffles - Replace any filters, baffles or covers that were removed.
10. Restore power - Restore power to the vent hood.
11. Test operation - Turn on the vent hood and test that the new main control board is functioning properly.

Repair Instructions:

If testing shows the thermal fuse is okay and the control board is getting power, the control board may be broken. But these boards are often assumed faulty when they actually still work. Before replacing the range hood control board, check other parts that fail more often first. Things like switches, motors, capacitors, wiring and fuses should be tested before the board. That's because those cheaper parts usually go bad more than the board. Only change out the control board if those components check out fine. Jumping to replace the control board can be pricey if it's not really broken. Make sure to troubleshoot the other common problem parts first before deciding the control board needs replacing.

Range hoods are usually wired directly to the circuit breaker box. But sometimes a hood is plugged into an outlet behind a cover panel instead. In both cases, testing if power is reaching the hood can be hard without removing a big cover first. If the hood plugs into an outlet you can reach, plug in a small appliance to check if the outlet works. If you can't easily get to the hood's power connection, look at the circuit breaker feeding the hood. Make sure it has not flipped off to cut power. Turn it back on if it tripped. That may fix the hood if the breaker was the issue. But if you can't access the outlet or wires, the breaker is on, and the hood still doesn't work, the problem is likely with the hood itself. More troubleshooting of the fan, lights and internal parts will be needed to find out what's wrong.
