I need to remove and clean furnace blower.

i don't know. it may be your blower or your motor that needs to be inspecvted. be very careful. shut off power to furnace. turn thermostat to lowest setting. shut off circuit breaker for furnace or remove fuse for furnace. open blower panel; and pull drive belt [ i f furnace has one ]
that turns the blower. if it turns, the blower is OK i suspect the motor needs repair. https://www.repairclinic.com/RepairHelp/Furnace-Repair/36-383--/Coleman-Furnace-Troubleshooting

Make sure your air filter is clean. Is the thermostat satisfied? or is the room temp. still below the thermostat setting? When ever you have to turn the power off and then back on to a furnace that usually indicates that the furnaces ignition control locked out. The first thing that I would try is cleaning the flame rod.

You will need to do additional trouble-shooting. This could be a faulty thermostat, a broken wire at the thermostat or a problem with the furnace. At the thermostat, check that the wires are fully seated at the terminals. Make sure that the conductors haven't broken. (I've seen the wires break after they weakened.) You can try placing a jumper between the terminals for heat and ground. (For a single-phase forced air system, the Rh wire calls for heat.) If your system has a C (common) wire, make sure that the voltage is getting back to the furnace. You can try a different thermostat.

Also look at the furnace. Some systems will have an LED indicating a problem with the unit. Gas systems can have a problem with the flame. Gas or electric forced air systems could have an issue with a blower. Heat pumps can freeze up if the temperature is below their operating range.

I hope this helps. Please add a comment with the manufacturer and type of furnace (oil, gas, steam boiler) that you have if you need more ideas for trouble-shooting.

(my own gas furnace went out on Wednesday and was temporarily fixed by resetting the thermostat and using a jumper across the appropriate terminals. The flame didn't come on at 6 A.M. when the thermostat called for heat. Today, the blower completely failed and needs to be replaced. The earlier failure is likely to be related to this failing blower motor. When I followed the manual's instructions for testing the system, I got a "needs service" code. However, the unit didn't display a trouble-code before I did that test.)

Should be a trouble code on the panel or in the literature book that came with unit. More than likely it's on the inside or outside of the blower panel. This will indicate Red light on Green light slow flash = what trouble code or issue it's having. Most common problems with a gas furnace is the flame sensor needs cleaning. There is a little rod that sticks down into the flame when the burners ignite. It's the only thing the flames will come in contact with besides the furnace itself. It will have 1 wire connected to it. Clean that rod with a piece of light grit sand paper. Don't take much force to clean it so try not to damage it by shining it to look like new. Cycle and see if it will hang in there. Hope this helps!

Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. Dirt affects all three basic components of your furnace, so cleaning is the most important part of regular maintenance. The three parts of the furnace should be cleaned: the filter system, the blower, and the motor.

The furnace filter should be replaced or cleaned at the beginning of the heating season and about once a month during periods of continuous use. To check the filter, take it out and hold it up to the light. If it looks clogged, replace it with a new filter of the same type and size regardless of the length of time it has been used.

Step 4: Clean blower assembly, belts and pulleys to blower, and motor housing. Cleaning blower is critical if furnace has a squirrel-cage fan, because openings in this type of blower often become clogged with dirt. To clean blower, remove panel that covers filter to gain access to blower or panel on front of furnace. This panel may be slip-fit on hooks or held by series of retaining screws. Access to inside of blower is usually gained by sliding out fan unit, which is held on track by screws.

If power cord to fan assembly is not long enough to permit fan unit to slide all the way out, disconnect cord. Mark wire connections first so you'll be able to reassemble unit correctly. With toothbrush, clean each fan blade and spaces between blades. Then, with vacuum cleaner hose, remove all dirt and debris loosened by brushing. Vacuum belts and pulleys. Wipe motor housing clean to prevent heat buildup in motor.

Need your model # to check the codes but, this coming back on after turning the t-stat off is rare. You may have been in a lockout and the furnace re-started. Some furnaces try to start three times , then lock out. Time out, then re-start. The codes should be on your furnace blower door. Write back with this info and i could help.

Generally ther is two screws at the base of the blower housing which hold it in place, remove the screws and pull, slide the entire assembly out. You will have to disconnect the electrical wiring to the blower and possibly the limit switch on the side if equip.

Your furnace may be kicking out on high limit. Its possible your circ. or blower fan needs to be cleaned. If you don't get enough air moving across you heat exchanger it will kick off on high limit.

Hello,
Check the pressure switch and the little hoses going to the pressure switch. If the pressure switch does not get a vacum from the blower it will not let the furnace light.
