How to fix el296uhv: what the display and the diagnostic button are telling you: step by step

1. Watch the display with the furnace idle: a blinking dot means idle. C, H, d, h or dF followed by a number means a call is running.
2. To read stored errors, hold the button until E shows and release. The last 10 codes scroll. Choose c and press again while it flashes to clear them.
3. To check the flame sensor, hold until F shows and release. Normal is 2.6 microamps or more. 2.5 or less is low. Drop out is 1.1.
4. Hold until three bars show to go back to normal. Menus time out on their own.
