I am not sure if you have gotten this issue corrected, or not, but the first thing I would try to do is to reset the heater computer system. This sometimes corrects and EO4 error code.

What you will do is open the right hand side door and find the POWER toggle switch, turn that off. Then find the CIRCUIT BREAKER for the heater and turn that off as well, then wait about 15 to 20 minutes. After waiting, you will turn the CIRCUIT BREAKER on first, then the heater. Try and start the heater up.

If the EO4 code comes back, there may be an issue with the heater. If the code does not come back and the heater starts, then the error code was what I call a "computer hic-cup".

The hot tub Hester will not light up pilot but does turn on and bow cold air


Glenn,
Many things could be wrong. First off, the exhaust fan turns always goes on when you turn on(up) the thermostat. It does that to suck out any residual gas in the combustion chamber. After about 10 seconds you should hear a click which is the gas valve opening to let the gas into the chamber. You should also hear a series of clicks for about 10 sec, which is the electronic ignition firing. If you hear the clicking of the ignition, but do not smell gas from the exhaust, then the gas feed is being blocked. If you don\'t hear the ignition clicking then the computer board is detecting a fault condition by one of its sensors: over-temp, water flow, exhaust fan . These are all in series and if one doesn\'t pass then the ignition won\'t fire.

Electrical - won't start. Hooked up fan to heater, smoke came out from under the hood, car won't start. Lights work, any key related electrical functions won't work


Your fan or heater likely shorted out and burned up, causing your one of the main fuses to blow due to the spike in current. You will need to determine what burnt up and replace it before replacing the fuse, or you may create a fire hazard or cause further equipment damage. Also double check any changes to wiring to make sure that everything is hooked up properly.

DAYTON 210,000 BTU OIL-FIRED HEATER WON T LIT UP


You write "FUEL SPRAYING AND FAN WAS WORKING"

If the fan was working, but the fan is not working now after replacing the whole kit, then something was installed incorrectly during the installation, possibly the rotor gap or rotor thickness is not correct or vane/vanes installed 90 degrees off.
