Decoding Lennox Furnace Error Codes: Common Issues and Fixes
The first step in figuring out how to fix an issue with a Lennox furnace is to decode Lennox furnace error codes to get a better understanding of what is happening with the unit. Identifying the type of code and understanding potential causes can help ensure the right steps are taken to repair or install a new furnace system. These codes are specific to Lennox furnaces, and understanding them is a crucial part of maintaining home comfort.
Identifying Common Error Codes
Lennox furnaces have several common error codes assigned to them, which are displayed based on the problem the furnace is experiencing. Some of the most common Lennox error codes include E1, BL, L2, OOL and LF. Each code is specific to a different issue, from pressure switch problems to an issue with the furnace's fans.
E1: An E1 Lennox furnace error code is indicative that a problem is occurring with the pressure switch. The pressure switch is linked to the inducer fan and when the fan cannot form a seal, the pressure switch trips which causes the E1 code to appear.
BL: A BL code stands for "burner lockout" error code and it typically means that a limit has been hit. This limit could be caused by a lack of airflow, blocked venting or an issue with the flame sensor.
L2: An L2 code means the furnace does not have a furnace flame on the first or second stage. This is usually due to the furnace's rollout switch being tripped, resulting in the L2 code being displayed.
OOL: The OOL error code is associated with the rollout switch being tripped too often. If there is an issue with the furnace's flame, it may cause the switch to trip more often, resulting in the OOL code.
LF: An LF code is associated with a problem with the furnace's fans. Both the inducer fan and blower fan must be operating properly in order to make sure the furnace is functioning properly. If either fan is not working, the code LF will appear.
Common Issues and Fixes
Common issues with Lennox furnaces, and their associated error codes, can have some very basic fixes that can be done at home by homeowners. However, many issues require the expertise of a skilled HVAC technician.
E1: To fix an E1 error code, the first step is to check the inducer fan to make sure it is running. If it is not, the owner should reset any circuit breakers that have been tripped and make sure the furnace's power switch is turned on. If the issue persists, the issue is more than likely not caused by the inducer fan.
BL: An easy to fix technical issue with a Lennox furnace experiencing a BL error code is that it needs to be reset. This can be done by switching the furnace off, waiting 30-60 seconds, and then turning the power switch back on. If this does not work, a professional HVAC technician must be called to identify the cause of the problem.
L2: The first step in fixing an L2 code can be checking the furnace's flame sensor to make sure it is clean. If it is dirty and not reading properly, it must be cleaned with fine sandpaper or replaced completely. If the issue persists after cleaning, a professional HVAC technician must be called.
OOL: For an OOL error code, the most common cause is faulty wiring in the furnace's circuits. This requires professional attention and should not be done by a homeowner.
LF: An LF code can be caused by a faulty thermostat. The easiest solution for this is to switch the thermostat out with a new one and check if the issue is resolved. If the issue persists, the furnace's motors, wiring and other components should be checked by an HVAC technician.
