It saying ee8 blower on da laser 73

EE-8 is for a blower motor malfunction. It could be due to carbon build up on the exhaust fan blades. Remove the front cover of the heater. Now locate the blower. There is a black rubber boot that goes from the bottom of the heater to the blower. Remove that boot. Use your finger or a pencil or whatever to reach in the hole and turn the fan blades. You may here a crunching sound from the carbon breaking up. Turn it until it frees up. If it turned freely to start with, you probably need a new blower motor. If it was hard to turn and you free it up, you will probably be OK.Let me know what you find. I have a used blower for a Laser 72 that should work for your Laser 73.

The heater operation is very noisy compared to new. Perhaps it's the fan? The heater is six years old and I'm concerned that it may cause a fire.

Its most likely the bearings in the fan motor failing causing vibration. One simple way would be too check and make sure all nuts and screws and bolts are tight around th e fan. If so is the fan blade dirty it doesnt take much dirt on a fan blade to get it out of balance and cause bearing failure.

Error EE 8 is showing what could be the problem???

EE 8 indicates a problem with the combustion blower. If the blower is running the problem is with the sensor. Make sure the wires for the sensor haven't come unplugged. If the sensor is bad, you will need a new blower. If it isn't running then the problem may be soot and carbon build up on the exhaust fan blade. You will have to remove the fresh air hose on the back of the heater or the rubber boot inside the heater to reach the fan blades. Use your finger or something to reach in and turn the fan blades. You may hear the sound of the carbon breaking loose. Turn it until it spins freely. Let me know if you need anything else.

Noisy when operator...especially during start-up. A deep rumbling...a bearing wearing out? Vibration...something loose Thank you.

Depending on how much the heater has been used, you may just have carbon/soot built up on the exhaust fan blades. This can be remedied by removing the blower assembly and cleaning the exhaust fan blades. They are the set on top. If could also be a bearing as you suggest but I would check the fan blades first. Let me know if this doesn't fix the problem.

Outdoor unit hums but fan doesn't turn. Nothing heats up but the fan just won't turn and is there a spot to oil the fan on the motor

The fan motor on the outside unit should be a sealed motor. If the unit is just humming is the humming from the compressor or from the motor being locked up. You could try spinning it a few times with the power off to see if this might get it to run and spray some penetrating oil under the fan blade right where the shaft comes out to the fan blade.

Unit is very loud. sounds like motor is going out

HI. Just so you know, Hissing and popping is normal on frost free refrigerators, it is the defrost heater, in this case. I would check these following areas to address any other abnormal noises.

If the level of the unit is not adjusted to proper specs, this will create an unstable operating condition, causing many noises to emit from the units structure. inspect the unit for proper level. adjust if needed. Next will be the drain pan. Once removed for cleaning, the pan must be replaced in position correctly. If not, the pan will rattle against the compressor, causing a ping or rattle.Simply reposition the tray if this is the case. The third possible issue will be the condenser fan. The condenser fan is located behind the refrigerator. It may be necessary to remove an access panel to reach it. This fan has a shroud, and if the fan blade becomes warped, it will rub against the shroud, causing noise. This fan blade is whole,and it can be removed and replaced if this is the case. Ok, the fourth problem spot will be the evaporator fan.

The evaporator fan is located at the back of the freezer. It may be necessary to remove obstructions such as the contents of the freezer, freezer shelves, ice maker and the rear inside panel of the freezer. The rear panel may be held in place by retainer clips or screws. Remove the screws or depress the retainer clips with a small screwdriver. Check the fan for warped blades. if the blades are warped or mis-aligned, replace it. This fan also is protected by a shroud as well, and it will make noise if the fan blade is damaged.

Last, i would move on to the compressor mounts. This is the most common spot for noise overtime. The compressor sits on rubber mountings. Those rubber mountings are designed to absorb vibration from the compressor. As the mountings age, they can become hard or disintegrate. When this happens, the compressor vibration is transmitted to the refrigerator structure and it can cause noise.

The compressor is located in the rear. It may be necessary to remove an access panel to get to the compressor.

Locate the compressor and remove the screw or retaining clip of just one of the compressor mounts.Using a pry bar, lift up the compressor enough to slip out the rubber mount. Inspect the mount for deterioration. The rubber should be firm but not rigid. If the mount is crumbling or hard, it should be replaced.

This concludes the inspection procedure. Follow carefully, and replace any failed or damaged device.

NOTE_ If by the end of this procedure, you have come to the conclusion that the noise is indeed coming from the compressor, and the mounts are ok, this will confirm that the internal seal in the compressor has failed. This will require you to replace the entire compressor unit.

Heater motor,fan making noise

Check to see if something is in the fan blades that is throwing it off balance. Also check the belt to see if it is ready to break.
