2478A Frigidaire Range - Instructions

First I had to slide the stove out of its cubby and then I removed the two screws holding on the shield. I next removed the wires going to the spark module. I removed the top screw and loosened the bottom one. Installed the new spark module in reverse order. Less than 15 minutes for whole repair. Still have problems with spark module not working if oven is on, but I think it is because there is no air circulation behind the stove.

Warning- we found a lot of bare wires in this stove, check your wires before replacing the bad switches. I lifted the top, disconnected the power, pulled off the knobs, unscrewed the switch for the back light, removed seven screws to finally get the front panel off. Once you have the front panel off, changing the swich takes less than a minute. The switches just slide off the gas valve stems. Instructions show how to line up the new D-shaped switch mechanism to match the D-shaped shaft. Gently pull the two wires off the old switch and slide onto the new switch. Then put the panel back.

Our original oven ignitor went bad. The gas supply won't even open, unless the oven senses the proper voltage / resistance across the ignitor, so that gas won't be flowing without ignition.

PartSelect was very good about providing me with the proper part, after I got the part number from their schematics and wiring diagrams, on the website. The first replacement part actually arrived, broken, from shipping, but when I called them, they immediately reprocessed the order, and sent me a new ignitor, to arrive the following day. I was very satisfied with their professionalism, as I've been in the past with them, as well.

On to the actual repair:

I removed the broiler drawer from the drawer slides, reached under the main oven chamber, unscrewed the two screws holding the ignitor in place, and cut / disconnected the two wires supplying the power to it.

I then put the new ignitor in place and screwed it back to the mount, used the wire nuts that came with the new ignitor to reconnect / splice the wires, and put the broiler drawer back in place.

Oven fired right up!

Entire process took less than 35 minutes. (Likely would've taken a bit longer, but this is the second replacement for the ignitor, since we've owned this oven, so I already had a good idea how to do it. (The first replacement for this particular part was NOT from PartSelect, so we're hopeful this one lasts a while longer than the previous one.)

Thanks, PartSelect!

Slide out the old; slide in the new!

I searched the item I needed and followed a link to PartSelect.com. I paid a little extra for shipping and literally recieved the part in two days. The part was an absolute perfect fit and my wife and myself have never been happier. Home cooked meals again thanks to the folks at PartSelect.com. It couldn't have been an easier.

First had to move the stove out of its "nest", take the side cover off, remove 1 screw and loosen the other , take the old module out and reverse the operation. That simple.
Part was supplied 1 day before promised date, awesome. Part fitted exactly as the OEM part, works like a charm, everyone happy.

1) Turn off the gas and disconnect the power

2) Remove oven door. There requires that you remove the two square drive (SD) bolts on the inside, partially close the door and lift it off the hinges.

3) Remove the grills.

4) At the back remove the rear shield (aluminum panel held by 2 SD sheet metal screws.

5) this exposes the broiler igniter and its two wires. If its been replaced in past, there should be two porcelain screw-on wire connectors. Undo the connectors by turning them counter-clockwise. With a volt-ohmmeter, measure the resistance across the igniter. If its open circuited, its broken. If not, then its in the circuit board, and this help stop here. If this is the original igniter, it ends in a plastic connector. Disconnect by pulling it apart from its mating plug and again, check the continuity of the igniter. If its defective, reconnect the connector and cut each wire on the igniter side. Strip back about 1/2 inch of insulation on each lead.

6) inside the oven, using the SD driver, remove the 4 screw securing the broiler burner from the roof of the oven. The burner can now be removed, pulling the burner away from the gas jet on the right.

7) The igniter is now exposed and can be remove by removing the two SD drive screws.

8) Replace with the new igniter, being careful not to touch the black element, and feeding the wires though the rear oven wall.

9)Reverse the above dissembly procedure.

10) Broil the sausages.

Make sure you unplug the oven before you begin. I removed the old igniter. The top wire on the igniter goes to the back of the oven and plugs into a flat blade type connector. Instead of using the twist wire nut I used a flat connector because it was easier to put on and is foolproof. Make sure you cut the plastic insulation off the connector so it does not melt when the oven is in use. I used a wire nut on the other wire and that was it. Very simple and the oven works great again.

removed shelves and base, removed 2 screws that held igniter on, disconnected wires from gas valve removed protective cover in corner {1 screw}
disconnected plug, removed igniter. This igniter was easier to remove from front of stove on this model

Bought two to try out to see if they fit and worked-popped out the old ones and the new ones fit and worked like a new stove. Came back to this web site and bought the other two so all burners are now brand new without having to replace the stove.

First, I unplugged the oven from the wall. I opened the bottom drawer of the oven to see where the igniter was mounted, which was directly under the bottom pan of the oven itself. I opened the main oven door and unscrewed the 2 screws that were holding the pan to the bottom of the oven. Then, I slid the pan back towards the the back of the oven and it popped right out.

There were 2 hex screws that were holding the old igniter on, so I unscrewed them with my socket set. I made sure to pay attention to which wire was the top one and which one was the bottom one coming out the back of the igniter. I pulled off the wire nuts connecting the igniter wires to the wires of the oven. I striped the wires on the new igniter and re-attached them to the proper wires of the oven, using the included replacement ceramic wire nuts. I re-screwed the hex nuts in, mounting the new igniter to its proper place. I put the pan back and screwed the 2 screws back in to hold it in place.

Plugged it back in, turned it on, fired up within 20 seconds. Good as new.

Twisted replacement bulb into place easily. Let there be light!

Removed oven door. (Open to first position then lift the door straight up). Located igniter in bottom of oven, followed connecting wires to connection block below oven behind the oven drawer. Disconnected the existing wires. Lifted the burner out of oven to disconnect defective igniter. Screws were fused to the burner. Used vice grips to remove screws requiring the screw holes to be retapped. Bought new screws to replace trashed screws. Installed new igniter to the burner rail then set burner rail back in place. Fished the leads from new igniter back down to connector block. Reinstalled leads. Reinstalled oven door. Tested functionality of oven. Everything worked. Reinstalled metal plates back in oven. Reinstalled cover over connection block behind bottom drawer. Reinstalled drawer. With the exception of fighting with two screws fused to the burner rail it is a very straightforward repair and shouldn’t take much more than 1/2 hour.

Ordered new racks and replaced them.

Determined how to proceed to disassemble the console. Unplugged the power cord, shut off the gas valve, removed six philips head screws from back panel and one philips head screw from side panel that held the front glass cover in place. Removed the nut off of the old switch body and the two oven control knobs and the timer/clock knob. Removed the front glass by pulling the right side forward and sliding it slightly to the right. Disconnected the two wires from the back of the old switch.Removed the nut holding the old switch body to the console frame. Replaced with the new switch and did a reassembly by backtracking my steps. I even remembered to clean both sides of the control console glass before reinstalling it. Placed the range back in position, checked it for level, plugged the power cord in and checked for the proper operation of the new switch, turned on the gas and checked for any possible leaks from moving the range. The switch was a perfect match. The picture on the grid paper background really helped in identifying the switch that I needed.
