The codes are usually explained on a wiring diagram that is on the back panel.
Check yours, it might be different! For me, a continuously blinking light is normal.
- Flashing slow: Normal – no call for heat
- Flashing fast: Normal – call for heat
- Continuous on: Replace IFC (circuit board)
- Continuous off: Check power
- 2 Flashes: External lockout (retries or recycles exceeded)
- 3 Flashes: Pressure switch error
- 4 Flashes: Open limit device
- 5 Flashes: Flame sensed when no flame should be present
- 6 Flashes: 115 VAC power reversed polarity or poor grounding
- 7 Flashes: Gas valve circuit error
- 8 Flashes: Low flame sense signal
- 9 Flashes: Check igniter
FYI, for a modern furnace, Never attempt to light your furnace manually. It likely uses a direct ignition system so when power is cycled, the pilot will then ignite automatically. It’s better to just call your gas company if there was an outage.
There are many apps to stream from computer to phone (AirStream: Stream PC over Air or SoundWire) but I want to listen to a podcast or music using my Android phone but listening on my computer or headset. It’s a good thing you can play the song wirelessly using Bluetooth on both the devices.
- Install Microsoft Windows Mobile Device Center.
- Turn on Bluetooth on the computer and the phone then each of them visible.
- Right-click on the Bluetooth icon in the Windows system tray and select the option Add a device
- Pair your phone and your computer with each other.
- Right-click on the Bluetooth icon in the system tray again but now select Show Bluetooth Devices.
- Right-click on your paired phone and click on the Bluetooth Operations.
- (If A2DP support is available on the phone, it will show an option to Play Music under Audio and Video operation.)
- Click on the link to activate.
- You should now have a player control will appear on your taskbar (If not, try and right-click on the taskbar and select Bluetooth Remote Control under the Toolbars)
