Furnace 33 error code


Why is my furnace going off on high limit?

Dirty air filters are a common cause of furnace cycling problems. Air filters trap dust, dirt and debris. With time, the filter becomes clogged and restricts airflow to the equipment’s heat exchanger. When this happens, the heat exchanger overheats, forcing the high-limit switch to trip and the furnace to cycle off.

How do you read a Bryant Furnace error code?

Like many furnace manufacturers, Bryant uses flashing LED lights to indicate error codes that can give you an idea of what’s wrong with your furnace when it’s not functioning properly. The short flashes indicate the first digit of the two-digit code, and the long flashes indicate the second digit.

Do all furnaces have a reset button?

All furnaces are equipped with a reset button. They are generally red or yellow and are located inside the blower compartment. The reset button is a safety feature that will shut down the furnace when a problem is detected, often a hot or overheating furnace, before it trips the circuit breaker.

How do you fix a furnace ignition lockout?

Most modern gas furnaces can be reset by turning off the power, waiting around 20 seconds, then switching the power back on. Other furnace models may exit lockout after 1-2 hours and attempt to power on again. If your furnace has a pilot light, you may need to relight it following the manufacturer’s instructions.

Where is the reset button on Carrier furnace?

Press and release the raised red button at the center of the flame roll-out switch to reset the furnace. You can press the reset button up to three times before troubleshooting the furnace’s internal components or calling for repair service; allow 30 minutes between each reset.

How do I know if my limit switch is bad on my furnace?

If the high limit switch was bad, the furnace should not fire. When the high limit switch trips, the flame/heating element will be shut off and the blower will continue to run to clear the heat. The blower will continue to run until either the system is reset, or the limit switch closes.

How do you know if a limit switch is bad?

The switch should be immediately suspect if the voltage drop is 0.2 VDC or higher (Fig. 1 indicates a bad limit switch). Verify that your ohmmeter will read “0” when the two leads are shorted together. The meter should read between “0” and “0.1” Ohms.

How do I read my Bryant model number?

Remove the front door and look inside the unit. You should see the model number printed on rating-plate or decal.

Can hear your furnace click on but it does not fire up?

Most likely, your furnace is making a clicking noise and not providing heat because your furnace’s spark igniter is trying to ignite your pilot light or burners but is failing to do so. In other words, there’s an ignition system malfunction that needs to be fixed. Otherwise, your furnace won’t start.

Does a Goodman furnace have a reset button?

Press and hold the red “Reset” button in the center of the rollout limit switch component. Hold the button for one to two seconds before releasing it.

How much does it cost to fix a furnace ignitor?

This repair typically takes up to three hours and can range in cost from $180 to $300.
