Hi I'm Vance and welcome to Repair and Replace.
If your oven display isn't working, and the oven won't heat,
it could be a problem with the thermal fuse or the control board.
Before we begin troubleshooting, it's best to check a few simple things.
Test all of the functions on your oven, including
the bake and broil settings, as well as each stove element.
If nothing works at all, then it's an issue with the incoming power.
There's more information on this no power scenario in the video linked below.
Since the stove elements run on separate circuits they are not affected by the control board.
So if the elements are working then you verify that your range
is supplied with the full 240 volts of power.
If you had a recent power outage then it's worth trying a reset.
Turn off the breaker to disconnect power.
After five minutes, turn it on again.
In some cases this will reset the control board.
Additionally it's possible that the clock just isn't enabled.
Pressing the clock button for five seconds will usually turn on the display.
This will work for most models but check your manual for the exact steps.
Now if this didn't fix the problem then you'll have to do some further troubleshooting.
In this episode we'll learn how to access and test the thermal fuse.
We'll look for faulty wires and inspect the control board.
Let's get started.
To begin, you might need a screwdriver, a nut driver, gloves and a multimeter.
Keep in mind there is some variation between models,
and not all ovens will have the same parts.
You can enter your model number on the AMRE supply website to see a parts breakdown.
This can be helpful to show you which parts are in your oven and where they are located.
Always be safe and disconnect the power at the breaker.
Since there might be some sharp edges, it's best to wear cut resistant gloves.
Gently pull the range slightly away from the wall.
As soon as there's enough room, go in behind and unplug it from the receptacle.
Make sure that there isn't too much tension on the cord.
Now slide the range all the way out so you have plenty of room to work.
On the back of the oven is a cover panel.
Some models have a small panel near the top and a larger panel near the bottom.
Now remove the screws.
The panel will likely be sitting on several hooks simply lift up to remove the panel.
Some ovens use a thermal fuse which will disconnect power if the temperature gets too high.
How this fuse is connected will change which part of the oven loses power.
In some models a blown fuse will just cut power to the heating elements
while keeping the control board unaffected.
In other models a blown fuse will cut power to the control board and display.
The fuse can be tested for continuity with a multimeter.
A continuity test will determine if there is a continuous path for electricity to flow through.
First disconnect the wires and isolate the fuse.
Set the multimeter to the ohms or resistance with tone setting.
Now place the probes on each terminal.
If the fuse is good the multimeter should display between 0 and 1 ohm.
If the multimeter doesn't show a reading or doesn't beep,
then there is no continuity and the fuse should be replaced.
Now unscrew and remove it.
Next replace the thermal fuse and tighten the screw.
Now reconnect the wires.
If the thermal fuse is good or if your oven doesn't have a fuse,
then check the wires leading into the control board.
Starting at the terminal block trace the lines up to the board.
Look for any burnt or frayed wires.
If the wires are damaged, then it's best to repair that section.
You can also test each wire for continuity.
Starting with the red wire test from the terminal block to the control board.
Now test the black wire, if either wire fails the continuity test
then you'll have to repair the wire or replace the wire harness.
If you have eliminated all other problems and the oven's still not working properly,
then it could be a problem with the control board.
First do a visual inspection of the board.
If you see any charred or blackened spots then it's a good sign that there's a failed component
or short circuit in the board.
If you had a power surge recently that could be the cause.
As well, double check that all the wire connectors are secure,
as a loose connection can prevent power from going to where it's needed.
Overall these boards are pretty simple to replace, but are non-returnable after installation.
So if you're not sure that the control board is faulty it's best to call a professional.
Align the back panel and replace the screws.
Now plug in the cord and push the range back into place.
Next reconnect the power.
Now you can test your oven.
