York Furnace 3 Red Flashes
York Race 3 red diagnostic light? 3
Hello,
We have a house in the attic to heat rooms in York. One day a strong wind was blowing and then the engine stopped. It has three red diagnostic lights, which means.
The pressure switch is bad, the pressure switch is bad, the ventilation duct is closed, or the inductor is bad.
When the heater receives a signal from the thermostat to provide heat, you can feel the light air coming out of the room vents for a minute and then feel the shutdown.
We are beginners and we do not know what to do ... Can anyone guide us?
Also, the machine is under warranty, but the parts are not, we also extend our warranty ...
Should I call ... should the warranty be extended? Generation guarantee? Or are you sure? Or just call a technician and fix the problem?
Thank you for your help.
In strong winds, air may pass through the vent pipe and the inductor motor may not be able to pass enough air. If it is turned off more than three times in soft safe mode, the card will lock the device. Try turning off the computer for a few minutes to reset the card and turn it on again. If the problem persists, contact the rebel company to investigate. I will check the warranty extension and warranty extension. I don't understand the warranty, but I don't understand the parts. Maybe some part of it exists and it doesn't. If the device is not older than 5 years, the parts must be covered. I now.
All of these parts can be damaged and the machine will not work without them. Find out when your extended warranty expires and contact them. They will tell you which contractor you should contact. You don't have to spend anything to fix it.
