Question about Dayton Heating & Cooling

Open Question

Furnace Blower Cartridge Sleeve Bearings. I am replacing 3/4" Dayton Cartridge Sleeve Bearings in my current blower and need to increase the RPM from 1,000 to 1,200 RPM to run the A/C. The bearing spec. is 1,000 RPM. Is there enough safety factor to run these bearings at 1,200 RPM without decreasing the bearing life? I've tried it before without the bearings getting hot. Thank you.

SOURCE: Furnace Blower Motor Specs

That information is usually on the data plate on the furnace and on the motor itself. All you need to know now is the HP. Other than that a universal consolidator motor is an easy fix too. It can handle 1/6-1/3HP.

SOURCE: where are the bearings that

There may not be any access ports to these bearings...
Most new motors today do not expect to be lubricated in their life's expectancy.
If the bearings are designed to accept oil, there will be either an obvious hole on the top side, (so that gravity can pull the oil down into the wicking or packing box..)
If not-- there is no way of 'oiling' them--

So-- Are you having problems, that tell you that you need to lubricate these bearings?
Like squealing or squeaking-- or 'dry' sounds when the motor slows down?

No problems, would like to find out the best way to remove blower for cleaning on an intertherm gas furnace mgh 075 ina mobile home

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.

Furnace blower runs continuously but no heat

sounds like the furnace control (low voltage) circuit is open, or in other words you either have a fuse blown or a limit switch that needs to be reset. Most newer furnaces have a small knife like fuse, usually 3 or 5 amp located directly on the circuit board. Limit switches that have a manual reset are usually located in the fire box just above the burner. There may even be a limit switch located on the blower assembly. If you fuse was blown, you may need to find out what caused the short in the circuit or it will do it again. If the limit switch was tripped, you need to turn the furnace back on and watch the flame to see if there is "roll out". It it continues to trip or blow fuses you need to have the unit serviced.

Furnace will kick on, begin heat up, go to the point where the fan should start and the whole thing shut down. If I move the thermostat down below the temp it show, it will start again and do the same...


Sounds like the blower motor is bad and then the unit is kicking off on high limit....

Probably nothing you can do with out getting a new motor to replace the bad one...

The pole buiding 24 in hanging Dayton sometimes the blower comes on like after 5 minutes after everything else kicks in and sometimes like when its supposed to and sometimes not at all?? All the electric...

I'm not sure whether this is a gas unit or not. With many gas heaters, the blower comes on when the heat exchanger gets hot enough and goes off once the heat exchanger cools. Other things are happening before the blower goes on. The blower is normally controlled by a "fan control thermostat". This stat actuates the blower when the furnace is hot enough so that cold air is not being blown around and allows the blower to run until the furnace cools enough to get out the remaining heat after the flame shuts off but not so long to again allow cool air to blow around. If this fan control is malfunctioning, you will get erratic runs from the blower or the blower may not run at all or run long or continuously. The fan control is the first thing to check.

With Model #GF9s120d20up11g, gas furnace, the blower model behind first top access door is very hot but furnace won't ignite, what"s the problem?

You did not mention if the blower is turning or not. If so, take a jumper wire and jump out the pressure switch to see if the igniter glows. If so, you either have a bad pressure switch, the inducer motor (the hot one) is not blowing enough to close the pressure switch, blockage in the condensate hoses or blockage in the vent system. If the blower does not turn, replace it.

No fan

Their may be several problems here. 1. The Thermostatic fan control in the furnace may be bad or.. 2. The fan motor could be defective or.. 3. The circuit board which controls all operations of the furnace could have burned out or.. 4. The blower compartment door is not closed completely.

Think with me Kiki.. If you have removed the blower door to replace filters lately, then #4 is most likely. There is a button that will be depressed when that door is closed correctly. It is very sensitive, and very common to your problem. Make sure the door contacts this switch/button. A schematic of the furnace can be found on the back of this door. If you need more advice get back to me.
