Main oven motor cover

If the main fan motor is screaming in your lincoln impinger oven, actually that means the motor is faulty. more so the bearing in the motor are worn out and should be replaced, its easier to replace the motor itself but the motor is very expensive. To save money you can actually replace the bearings your self by opening the back cover in which the motor is mounted, then unmount the motor and disassemble it so you can take out the bearings. take the bearings as a sample to a bearing store so that you can get the size correct.
make sure you get bearings that can handle high temperatures and not those with plastic seals ment for wet or water places.

Remove the cover at the rear of the oven compartment, then holding the fan blade with one hand, undo the nut holding the fan on, it is a left hand thread, so turn the nut clockwise as though you were tightening it.
To remove the motor itself you will have to undo 3 screws securing the fan motor from inside the oven compartment, then remove the outer rear cover of oven to remove the motor.

Is it the rear of the oven or the left side?

• Rear of the oven, it is a obstructed or malfunctioning axial fan. Replacement cost $10-$20 - 30 minutes labor
• Left side of oven, possible main blower fan malfunctioning. Depending on type of motor "S" or "Q". It might be the mount or a bearing wearing out. Replacement motor $200-$400, motor shop rebuild instead $150. Squirrel cage will need to be removed if damaged $100-$300. Labor 2 hours, if you know what you are doing, 4 to 6 if this is your first time. Check your heat slinger also. This might have come loose.

Call me for parts or further info. I have been here before.......

Hi,

Firstly, you don't need to replace your fan simply because it's noisy. It may be sufficient just to grease the spindle/bearings.

The fan is located at the back of the oven and CANNOT be accessed from inside the oven. If you open the oven door, you will see a grille at the back of the oven compartment - basically just some slots and holes cut into the back panel. Behind this grille is the heating coil/element, then another panel, behind which is the fan/fan motor. Basically, the fan is right at the back, dead-centre of the unit.

To access the fan, you will need to remove the oven from the wall cabinet and remove the back panel. To do this, you first need to unplug the oven or, if it's hardwired, detach the cable from the outlet - power off please! Next, remove the retaining screws at the on both sides of the oven at the front - these are only revealed when the door is open. You should now be able to remove the oven from the wall cabinet by pulling it forwards gradually and feeding the power cable through as you do it. I suggest getting someone to help you lift it out as they are fairly heavy and awkward to hold/carry. Also wear some old clothes as the bottom of the unit can be quite greasy!

Put the oven somewhere safe where you can access the back of the oven easily. The fan is covered by a removable back panel. Undo the screws (about 10) around the edges of the panel and partially pull the panel away - taking care not to snag any of the wiring behind the panel. You will also need to remove the connectors to the main power cable to remove the panel fully. Make a note of the connections (or take a photo) to ensure you reconnect it correctly!

You should now have clear access to the fan. Inpsect it visually to see if the blades are broken and try spinning it by hand to identify where the noise is coming from. If the blades are sound apply some HMP grease around the spindle which rotates the fan. This can be quite tricky, so it might be easier to liberally apply some spray lube around the area. Spin the fan by hand a little to work the lube in.

Next, test the oven before putting it back into the wall cabinet. This can be done by replacing the back panel and plugging the oven into a socket or extension cable. If the oven was hardwired, attach a plug to the end of the cable. Turn the oven on at the minimum temperature and let it run for 5-10 minutes to allow the lubricant to work through. If the noise has diminished or gone, reinstall the oven in reverse order of the above. After refitting, I suggest running the oven empty on a low-mid temperature until the smell of lubricant has gone.

If the fan is damaged - or you can't get rid of the noise by lubricating it - then you will need to buy a new motor and fan blade. Fitting these is easy with the back panel removed as they simply bolt/screw onto the back panel of the oven and the wires just slide on and off. If possible, take some photos before removing the old fan/motor to ensure correct fitting of the new parts.

Please post back if you need further assistance.

Hope this helps.

There is another fan motor built into the top of the oven, this is the cooling fan, so that is what you can probably hear.
To access it, you will have to remove the top cover, and possibly the rear external panel as well.

When you say the main fan, do you mean the background cooling fan or do you mean the circulating fan in the bottom oven?
Do you have the handbook for this oven as the wiring diagrams are included in it. If you haven't, you can take a copy from my BT Digital Vault - all I need is an email address to register you.
Looking at the diagram, the power for the cooling fan comes via the timer board. If, as you say, the fan doesn't work at all, the timer board could have gone faulty.

most likly the fault is the fan blades touching the side of the circular hole,to test.1.switch of all power.2.when power is switched of try switching your oven to on position.if oven will not work then proceed3.if you can turn the fan blades by useing a thin piece of wood or simler.4 if when you turn the blades you hear a rubbing noise you might take a closer look if you have torch point it in if you see the blades touching or one of the blades touching it might be possable to to push the offending blade back very slightley useing the same piece of wood you yoused at 3.if this fails to solve your problem the fan moter might be ready to give up. I hope this can solve your problem.yours adrian.

no i have not

If this is a self-cleaning model it is possible that the movement of the mechanical parts are at fault. Toward the back you should be able to find the motor and drive rod. Check these first and yes, there could be a loose or faulty fan motor.

How long is the sound there ?
