However, there needs to be a clear indication of what the manual red light’s blinking indicates. There are, nonetheless, several error codes that you can utilize to identify a potential issue.

Trane XR80 Blinking Red Light Code Errors

Fast flashing signifies a regular call for heat, while slow flashing shows a normal no-call for heat. Constant on means changing the control, while steady off means testing the power.

Two flashes indicate a system lockout or reversed polarity; three blinks mark a pressure switch issue; four flashes do not turn on thermal protection; and a flame is detected with the gas valve closed by five blinks.

Additionally, a call for heat from the thermostat is indicated by fast and standard flashing rather than slow and regular flashing.

When the control board malfunctions, it is always on, meaning a replacement is required.

Continuous off, however, results in a power check, two system lockout flashes, three vent pressure switch errors, and four high-temperature limit device opening flashes.

There shouldn’t be any light when the flame detection indicator flashes five times. When it flashes six times, either the 115-volt AC electricity is inverted or improper grounding.

Finally, nine beeps indicate that the ignitor circuit has to be checked.

What Causes the Trane Xr80’s Blinking Red Light?

Your unit’s red lighting system may blink repeatedly due to several issues. They blame many problems for the fault, as described in the preceding codes.

There are plenty of them, such as a broken pressure switch, no electricity, no flame, no igniter, and no thermostat signal.

There are also problems with the gas value, the high limit switch and roll control, the circuit board, the voltage, the furnace light, and other things.

Allow us to review a few of these faults for better understanding.

  • Zero Signal from the Thermostat

Generally, flashing lights indicate that your thermostat isn’t sending a signal to the furnace.

If you notice the red light blinking several times, it could be a lost wire connection somewhere. Test out all your contacts and ensure they are tight and not causing any issues.

  • No Power Supply

If your unit no longer receives power, the red lighting system will flash multiple times.

So quietly go outside and check the circuit breaker box. Locate the breaker switch connected to the furnace. If you notice a disconnect, click it back on and switch it on.

But if the circuit breaker isn’t tripped and no power flows into the system, it indicates serious issues. In that case, consider calling a qualified HVAC technician.

  • No Flame

Your heating system can experience flame failure if insufficient gas or air keeps a steady, hot flame burning.

Most times, the problem could evolve due to clogged filters and a dirty burner chamber. Others include broken burners and too much pressure in the combustion chambers.

  • Igniter Issues 

Does your furnace still kick on? Still, see how many fins on your burner aren’t functioning.

If any of them are experiencing ignition failure, two things are involved. It may need to be replaced or repaired. The switch is typically designed to send a spark near the pilot light to ignite each flame.

But the furnace may be locked if there’s no flame at all. This will require an emergency heating repair service.

  • Issues with the Gas Valve

For those with gas-powered Trane Xr80s, this is another issue that can cause a red blinking light.

Such a problem occurs when there’s a fault with the gas coming in through your gas line. Or the gas feeding into the combustion chambers doesn’t have enough pressure to ignite.

When faced with either of these problems, you should adjust the knob. That way, there will be more gas coming through. But if you wish, a professional can check the system.

  • Problem with the Circuit Board

When the circuit board of your unit is severely damaged or has electrical issues, the red flashlight will blink multiple times.

If that’s the current condition of your heating system, swiftly contact an expert to make repairs. If neglected, it will do more damage than good.

It can sometimes lead to a fire outbreak, which can damage your assets or result in fatalities.

Is the red light on your Trane Xr80 blinking? That’s not pleasant news. As you can see, it’s a warning of several issues.

Fortunately, the error codes in this article will enable you to identify potential heating system issues.

Consider calling a qualified HVAC technician if the issue is beyond your control. But if resetting will solve the problem, you can check the user manual to see how to proceed.
