SOURCE: gas heater circuit board
On the bottom door where the blower foor is located,
look on the back of it. It should have a Electrical print
and at the very bottom A Troubleshooting chart for
the control board. It is hard to find but it is on there.
Usually a solid Red means system is ready and good
Good luck, if you need anymore help let me know.

Trouble Code 14 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally high readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operations among others. The thermistor used has a low resistance when hot, rising as the coolant cools. This error then, indicates a very low resistance in the CTS circuit.
Trouble Code 15 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally low readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operation, among others. The thermistor used has a high resistance when cold, lowering as the coolant warms. This error then, indicates a very high resistance in the CTS circuit.
Trouble Code 33 indicates that the Mass Air Flow (MAF) sensor is reporting more air is entering the engine than makes sense based on RPM and TPS. The MAF sensor produces a frequency output; around 30 Hz at idle to 150 Hz under acceleration. The frequency varies proportionally to airflow. The ECM monitors the frequency and thus determines airflow into the engine. Typical idle MAF is 5 to 7 grams per second.

Code "CE" stands for communication error and describes a fault between the mother board and the display. I doubt it's the relay causing it though...

I found this for a different model in the same family. Sharp AR-BC320 it may be the same as your problem.
On page 2 it says E7-21 is:
LED controller initial trouble (Cyan)
On page 4 it gives a couple of things to try to fix the problem.
