So, what do they mean? What does Carrier Furnace Code 31 Mean?Įrror code 3-1 (or 31) typically signals a problem with the pressure switch. However, the three most common error codes besides the blinking yellow light are 3-1, 1-3, and 3-3. You ca rectify these situation by checking the secondary voltage wiring. Some of these carrier furnace error codes include carrier error code 1-2 signalling that the blower is ON after the power-up and carrier error code 1-4, a sign of a secondary voltage fuse is open and there is low voltage. Carrier Furnace Error Codes (Others)Ĭarrier furnaces have many other error codes beyond the flashing yellow light. Instead, you need to find a licensed HVAC technician to help out especially when there is a broken internal component and the furnace is not producing heat or producing strange noises. Unfortunately, a gas valve solenoid stuck in high fire mode cannot be repaired. What to Do if Your Carrier Furnace is Blinking? The blinking yellow light flashes to alert you to take action. If it refuses to close when the furnace is in high-fire, you’re in trouble. However, the gas valve solenoid can fail, thus refusing to open or close. The replacement of control board is complex and requires a technician. The average cost of replacing a control board is between $300 to $600. There maybe a problem with the control board if you don’t hear a clicking noise when the unit is turned on. They are primarily incorporated into gas heating systems for increased safety and efficiency. The control board regulates the amount of voltage that reaches every part.

The gas valve solenoid helps control gas flow by using a plunger to open or close the valve, allowing the gas to pass or seal off the passage without leaks. However, the leading cause is a defective gas valve solenoid. The furnace can get stuck in the high-fire mode for several reasons. Reasons the Light on your Carrier Furnace is Blinking When you see this error code, the air flow won’t operate as it should. Four yellow light flashes on your York furnace means the heating system maybe restricted. The flashing yellow light is a safety mechanism designed to alert you that the furnace is stuck in high-fire. So, imagine if the furnace accidentally gets stuck in high-fire mode! It can be a terrifying situation. Running the furnace at 100% capacity for an entire hour, for instance, would quickly result in overheating, affecting both you and the furnace.

Fortunately, all Carrier models have this mode.Īs you can tell, though, high-mode isn’t entirely safe for livability and furnace health, especially over long periods.

If this is the case, you must wait for indoor temperatures to rise gradually. The bottom line is that it allows the furnace to raise indoor temperatures sharply over a short time, such as over a minute.Īt the same time, some furnaces don’t have a high-fire mode. High fire mode is usually 100% on most furnaces, though a few units can operate at up to 130% during high-fire. Engaging high-fire for a short period allows the carrier furnace to raise indoor temperatures significantly over a short period before it goes back to normal function. This is particularly necessary when the temperatures in your home are too low at the time the furnace kicks on. High-fire mode is a setting on the Carrier furnace in which the heater generates a lot of heat over a short period to “jumpstart” the heating process or heat a very cold house faster. The yellow blinking light indicates that the furnace is stuck in high-fire mode. What Does a Yellow blinking Light on a Carrier Furnace Mean? The low pressure switch problem can be rectified by cleaning the condenser coils. Although codes 31,33 and 13 are the most common problems, others like low pressure switch fault, reversed line voltage polarity etc. It helps to swing in swiftly to troubleshoot and ideally fix the issue before it creates a bigger risk. The reason it blinks is to alert you about the underlying issue. However, anytime it begins to blink, there’s a problem. As long as everything works smoothly, the unit will run without any blinking lights. No, your Carrier furnace light shouldn’t be blinking when it’s running. Should My Carrier Furnace light Be Blinking? However, what’s the specific problem when the light is yellow? What could be the underlying problem, and how can you resolve it? Let’s dive right in. Maybe the carrier furnace is locked out, or one of the parts isn’t functioning normally. When the carrier furnace is blinking yellow light then it’s sending you a signal that it has run into a problem.
