Osburn Stoves by SB I HYBRID-45 MF Manual Do Utilizador

 

When your stove acts out of the ordinary, the first reaction is to call for help. This guide may save time and money by enabling you to solve 

simple problems yourself. Problems can be caused by to only five factors: 1) poor fuel; 2) poor operation or maintenance; 3) poor 

installation; 4) component failure; 5) factory defect. You can usually solve those problems related to 1 and 2. Your dealer can solve 

problems relating to 3, 4 and 5. Refer to figures 26 - 29 to help locate indicated parts. 

 

 

 APPEARS ON CONTROL BOARD 

Possible Causes: 

Possible Remedies: (Unplug stove first when possible) 

 
1. 

Airflow  pressure switch hose or pressure tab for hose are 
blocked. 

 
Unhook air hose from the airflow switch and blow through it.  If air 
flows freely, the hose and tube are fine.  If air will not flow throw the 
hose, use a thin wire to clear the blockage. 
 

 
2. 

The air inlet, burn pot, interior combustion air chambers, 
combustion blower, or exhaust pipe are blocked with ash or 
foreign material. 

 

 
Follow all cleaning procedures in the maintenance section of the 
owner’s manual. 
 

 
3. 

Vent pipe is incorrectly installed. 

 

 
Check to make sure vent pipe installation meets criteria in owner’s 
manual and pipe manufacturer. 
 

 
4. 

The airflow pressure switch wire connections are faulty. 

 

 
Check the connectors that attach to the airflow pressure switch. 
 

 
5. 

The airflow  pressure switch wires are pulled loose at the 
connector on the wiring harness. 

 

 
Check to see if the wires are loose at the connector. 

 
6. 

Combustion/exhaust blower failure. 

 
With the stove on, check to see if the combustion/exhaust blower is 
running.  If it is not, you will need to check for power going to the 
combustion/exhaust blower.  Current reading may vary.  If there is 
power, the blower is bad.  If there is not, see #7. 
 

 
7. 

Control board not sending power to combustion/exhaust 
blower. 

 

 
If there is no current going to the combustion blower, check all wire 
connections.  If all wires are properly connected, you have a bad 
control board. 
 

 
8. 

Control board not sending power to airflow pressure switch. 

 

 
There should be a 120-volt current going to the air switch after the 
stove has been on. You will need a technician to perform this test. 
 

 
9. 

Airflow pressure switch has failed (very rare). 

 
To test the airflow pressure switch, you will need to disconnect the 
air hose from the body of the stove.  With the other end still attached 
to the switch, very gently suck on the loose end of the hose (you 
may want to remove the hose entirely off the stove and the switch 
first and make sure it is clear).  If you hear a click, the switch is 
working.  BE CAREFUL TOO MUCH VACUUM CAN DAMAGE THE 
SWITCH.
