However, in many cases it is best to call a HVAC company to replace the clogged section of pipe.Modern day high efficiency furnaces monitor a variety of conditions before, during and after the combustion process.
If the furnace is unable to achieve ignition for a call for heat, or if an unsafe condition is detected, the furnace will enter what is called lockout mode. What Does It Mean When the Furnace is in Lockout Mode As noted previously, furnaces monitor the entire heating cycle to ensure safe operating conditions exist. By utilizing sophisticated sensors, the controller will monitor the natural gas pressure, igniter and flame. When an unsafe condition is detected, the furnaces controller issues a command to discontinue further attempted ignition cycles and ceases operation or just leaves the circulating blower running continuously. When this occurs, often after two or three failed restart attempts, the furnace is known to be in lockout mode and will not attempt to run again until the furnace is manually reset. It is important to note that there are soft and hard lockouts, which does vary by manufacturer. Before jumping to the section on this page that details furnace lockout reset procedures, please view the important safety information and tips that follow underneath this paragraph. Not only do we want you to be safe, but we also want to help you identify what is causing the furnace to enter lockout mode so that it does not happen again. Conditions to Consider Before Performing a Lockout Reset If the controller on your furnace has detected an unsafe operating condition, or failure, you should first remedy the problem before performing a lockout reset. Though everything may look alright with your furnace, only a professionally trained HVAC specialist can perform thorough sensor and control board testing, while of course ensuring adequate gas pressure and ventilation system functionality exists. Though certain conditions may exist that you can correct to get your furnace running safely again, as discussed below, a HVAC technician has the tooling and diagnostic equipment readily available to identify many electronic problems. Identifying the Furnace Lockout Problem Many furnace models have a visual display that will generate a visible statuserror code. For example, some models will use a blinking L.E.D. Fine Hvac 10 Series Of FastSome of these units will use a series of fast and slow blinks to display the code while more sophisticated units may display an easily read alphanumeric code. To determine what this status code means, please write down the code consult your owners manual or call the manufacturer directly. In most cases system lockouts occur because of a defective igniter, flame sensor, faulty pressure switch or limit switch. Though these conditions often require a technician to diagnose and service the furnace, there are other simple problems that you may be able to correct in an effort to get your furnace up and running without the need for assistance. Correcting Conditions Causing Furnace Problems First, make sure your high efficiency furnaces vents are not obstructed. Though people using the PVC vent screens sold in our store are less likely to encounter this problem, others with wide open vents are more likely to suffer from occasional blockages caused by leaves, animals and insects. Ice may also cause a blockage, which is normally an indication of improperly sloped PVC vent pipes. A visual inspection of the termination vents should reveal any sign of obstructions caused by leaves and traces of animal or insect activity. Clearing the leaves away from a vent is a simple process, unless they are lodged deep within the pipe. If you can see the leavesdebris, or suspect that the blockage is in close proximity to the termination vents, a shop vacuum may be used to collect the debris and clear the blockage.
