5710 coleman blend air blower assembly

Postby Mezigore В» 07.04.2020

I have my eye on the BYOC Large Beaver, Musket, or ED Pig Hoof.

Click here for Blend Air II parts. Click here for operating instructions. Click here for installation instructions including wiring diagrams. Remember that when you start troubleshooting the system, this lever will need to be turned back on. The ventilation system not working is not considered an emergency and can be left off for a few days if necessary.

Leaving it off for a short period of time will have no effect on your furnace. Leaving it off for a long period of time may cause condensation to build-up in your attic and affect the air quality of your home. Because a typical mobile home is built fairly tight I know — your heating bill may say otherwise , a ventilation system has been added to bring outside air into your home. In the Deluxe model, the same system also removes moisture from your attic.

The control box for this Blend Air system is generally located in your furnace compartment or on the furnace itself. Part of the ventilation system is a pressure balancing damper. When the ventilation system is running, it creates a positive pressure inside your home. This vent is designed to keep the pressure equalized. Looking at the sticker on your control box will usually tell you which system you have. Unless the furnace blower is running, the damper remains closed. The relay is located inside the Standard Control Box.

The damper motor holds the damper open allowing air to come inside the furnace from the vent on the roof. Since there are no alarms, the only way you will know if the standard system is not working is by a visual inspection of the damper. If the damper does not open when the furnace blower is running, the system is not working.

This should start the furnace blower motor. Remove the filter on the air supply tube located at the top of the furnace. Look up into the tube. If you see the damper open, your system is fine. If the damper is closed, the system is not fine so continue to step 2. First check for 24 volts. If the motor is receiving volts, replace the damper motor.

The Deluxe Blend Air II system is more complex than the Standard Blend Air II because it includes an upper and lower control board as well as a blower motor on the roof that ventilates moisture from the attic. Like the standard system, the Deluxe also has the damper assembly. The Deluxe Blend Air system runs a cycle of 4 hours on and 4 hours off. Unless the furnace blower is running, only the the blower on the roof will run, ventilating moisture from the attic to the outside.

Whenever the furnace blower is running, the damper motor is energized opening the damper and allowing fresh outside air to enter the furnace. Besides the alarm, the control box will also flash a red light indicating trouble. Normally the problem is a bad control board or motor.

If you are not comfortable with understanding and using an electrical meter, please hire a competent technician to troubleshoot and repair the system for you. Remove the Deluxe Blend Air II control box from the wall and turn it around so you can access the lower control board.

Remove the red and yellow wires from the board. In earlier models, the yellow wire may be black. Turn the power to the furnace back on. If you are getting a reading of 24 volts, you have power. If not, then your problem is not the blend air system.

Shut power back off to the furnace and reconnect the wires to the lower control board. Turn power back on. Unplug the 4-wire adapter from the lower control panel. This should cause the attic fan to immediately start running. This may be labeled as Blend Air in your breaker panel, or in some instances, power to the fan is on the same breaker as your ceiling lights. You then may need to climb up on the roof and listen for the fan. If the attic fan is not running, jump to step 5. If the fan is running, that means the upper control board and attic fan motor are working fine so continue to step 3.

This is the same box and board where you just verified in step 1 that you were receiving 24 volts. Do the following checks:. Your meter should show DC Volts. If not, replace the board. If your doing the reading like the illustration shows, push hard enough on your test probes to ensure they make contact. Because of the 4-hour on and off cycle, it can be hard to tell when the attic fan is actually suppose to be running. Be sure power is off to the furnace before moving the jumper.

With the jumper moved, you should now hear the fan turning on and off every 30 seconds. First remove the screen at the end of the supply tube. Look up and you can see the damper. A damper is a door that opens and closes. You should hear some beeping again. If the damper opens, your damper motor is fine. If the damper does not open, verify that it is receiving 24 volts.

If power, replace the damper motor. Otherwise climb up on roof of home and locate the attic fan. The attic fan will be inside a metal vent and not too far away from the furnace chimney.

Remove three screws from the bottom of the metal vent and lift off to expose the attic fan. Go back in the house and disconnect the 4-wire plug from the lower control board. Climb back up on the roof and see if the attic fan is running. If the fan is running, this indicates that your attic fan and upper control board are OK. Sometimes power to the attic fan is the same breaker as your ceiling lights. If attic fan still is not running, reconnect the 4-wire plug and go to step 6.

Climb up to roof and verify that volts to black and white wires coming into the box. If volts, replace the attic fan motor. If no power at the MTR terminals, then recheck the lower control board as explained in Step 3. If still no power to the MTR terminals and the Deluxe Control Box is beeping and the red light is flashing, then replace upper control board. Test 1 — Check for 24 volts to the lower control board. This could be as simple as a loose wire, or one end of the 4-wire plug is loose.

The 4-wire plug connects to both the lower and upper control boards. Test 2 — One way to simulate 4 hours on and 4 hours off is to move a jumper socket from test to run in the lower control board. Be sure to shut power off to furnace before moving the jumper.

Now instead of running 4 hours on and 4 hours off, the attic fan will run 30 seconds on and 30 seconds off for test purposes only. If the fan still continues to run not stopping after 30 seconds , then recheck lower control board as instructed in 3.

Tip: when checking the lower board, check the DC harness voltage from the end on the roof that connects to the upper board see Test 3 below. If you are getting proper voltage at that end of the harness, then replace upper control board. Test 3 — If the upper board is not getting a signal from the lower board, the attic fan motor will run non-stop. This is the same as unplugging the 4-wire harness. The upper board not receiving a signal as noted in step 3 is likely caused by a defective lower board.

But do not rule out the fact that the end of the harness connecting the upper and lower board could be corroded or defective.

Check both ends and replace if questionable. When installing a new harness, add some special electrical grease to the pins to help combat corrosion. The system is no longer made and no longer being installed in mobile homes.

Most parts are still available for the system, but in time those too will be obsolete. The system operates using an upper and lower control board. Both of those boards are expensive and soon to be obsolete. The boards can be replaced with the Blend Air Retrofit Kit. To read more about this update, click here. I just want to thank you for the trouble shooting info on the deluxe blend air system. I was not only able to replace the blower motor on the roof but also diagnosed what caused the motor to go out.

The test jumper had been left in the test mode from install.

Look up continue reading the tube. Test 1 — Check for 24 volts to the lower control board. If not, then your problem is not the blend air system.

If the damper opens, your damper motor is fine. Unplug the 4-wire adapter from the lower control panel. Replaces the metal boxes.
