With Northern California’s cold weather in full swing, you rely on your furnace more than ever. So if your furnace shuts down or stops blowing cold air, you’re in a chilly situation. However, fixing the problem can be easier than you think.These 5 fixes can solve most furnace problems without you needing to pay for a repairman to come out.1) Change the furnace’s air filter if it’s dirtyIf the furnace filter gets too dirty, it will block the return air flow to the furnace. It’s like putting a blanket on your head and asking you to breathe normally.A dirty filter causes these problems:A dirty filter will also cause soot to build up in the heat exchanger, causing your furnace to run inefficiently and reduce it’s life span. Check the air filter every one to three months and change it if it’s dirty.REMEMBER: Turn off your furnace’s shut off switch (found on the furnace) and set the thermostat to off before changing the air filter.There may be nothing wrong your furnace at all.

Your thermostat, the control centre of your heating system, may be the culprit.If your furnace isn’t coming on or isn’t blowing hot air try these simple troubleshooting tips with your thermostat before you call a repairman:3) Make sure the blower motor panel is shutIf someone opened the blower’s panel to do a repair, they may not have shut the panel properly If it’s not pressed in all the way, a safety device will prevent the furnace from running. So make sure you securely shut furnace blower panel.4) Inspect your air ductsLet’s say your furnace seems to be working fine. Blower is running, hot air is coming out…in most rooms. You’ve got a few cold spots in your home. The answer is in your air ducts.First, check for handles protruding from the ducts. These are dampers that control the airflow. Make sure they’re fully open (i.e., the handle is parallel with the ductwork).If some of your rooms are still cold, your ducts may have gaps, cracks or holes in them allowing the hot air to escape.

This is what we call leaking ducts. These leaks not only make the room cold, but itFind where the leaks are in the ducts and seal them with a mastic sealant.5) Make sure the gas valve is openLike with the blower panel, someone may have shut the gas valve to do a repair and forgot to turn it back on on. If it’s off, no gas will enter the furnace, so nothing will burn. Simply turn it back on (the handle should be parallel with the gas pipe) ,and you’re good to go.When in doubt, call a professionalObviously, these fixes won’t solve all your furnace problems. So, if none of these do the job, it’s best to call a professional for help.If your furnace has a problem and you live in the East Bay, San Jose, and Sacramento area. contact Service Champions for help.Signs & Symptoms of a Bad Blower Motor Resistor The resistor of the blower motor is responsible for transferring the electrical current that's required to move air through the vents of vehicle. Blower motor resistors can wear out;

the blower motor no longer works correctly if this occurs. There are several symptoms that appear when the resistor of the blower motor is going bad. Recognizing these symptoms and replacing the resistor returns the airflow through the car to the proper levels.fan coil unit ahu When the resister of the blower motor starts to fail, the motor operates only intermittently. jeep wrangler ac compressor clutchThis often presents itself as the blower fan not kicking on until the engine is producing a certain level of electric current. 18000 btu split air conditioning unitsThe higher current can make the jump across the resistor contacts that are going bad and get the blower motor to engage. The blower motor could stop working again on longer roadtrips when the car is at a cruising speed and the electrical current of the motor drops again.

The lower settings of the blower motor require less electrical current to engage. But when the resistor of the blower motor is failing, it creates a larger gap between the connectors. This gap may be too far for the electric current to travel across. When this happens, the lower settings of the blower motor aren't able to function. The top setting of the blower motor may still be operational. Reduced airflow is when the blower motor is trying to move air through the vents but the resistor isn't sending enough power to move the air with much pressure. The blower motor resistor is receiving power but not the full force. Reduced air movement can occur at all of the different speed settings of the motor blower. Depending on how much resistor is still functioning, the reduced airflow could be an intermittent problem.Aurora Auto Body and Garage; Signs & Symptoms of a Bad Blower Motor Resistor; How to Troubleshoot a Blower Motor Resistor; Comments View all 8 Comments.
