Sounds like the controller is the problem. This is the circuit board that has the display and controls on it. You can swing that panel open and try tapping on the white plastic cover the controller is under that. This might get the fan relay to release but you will have to replace the controller it will stick again

Your EO4 message tells you you have a fan problem. So ether your fan is diying wich you would hear or you have a bad presure sensor in your exaust. A new fan is a little pricey but the sensor is reasonable for heater parts. I can't be sure but I believe it ether screws onto or into your exaust and it just plugs on to your control board. If your sensor is going bad their is a reason and this should be addressed. It should be in your by-pass or your gas pressure. But as far as a new heater, not untill you have water coming from the cabnit. It is sometimes easer to sell new than keep up with new, Good luck let me know how you do.

This sounds like you have a problem with your pilot. You can check this with a small mirror to see if their is a spark when you turn it on. If you have any soot build up on the pilot that will stop the spark and keep it from lighting also. If you have a short on your pilot wire this could be the problem also. I hope this helps, good luck.

If the fan was seized, it is likely bad, even if you freed it. If it doesn't sound the same, or is not as loud as it used to be, it is also most likely bad. If it doesn't move enough air to close the air pressure switch, then you will get an 04 fault, which is an air flow fault. HTH

This could be a water flo problem. you need to chech to be sure your by-pass valve is closed down enough to force water threw heater, There is a internal by-pass that could be a problem also, or a bad pressure switch. If the by-pass isn't the problem then you should check these also.
