P00012B Espar fault code

Modified on Mon, 29 Sep at 4:58 AM

To prevent the heater from locking out in the future, please wait for 3 to 4 minutes between each startup attempt. 


If the indicated 12B is the only code that is available, please try to delete it and try to run the heater once again. After the attempt to run it, please remove the 20 amp fuse (that is responsible for the heater) and wait for 20-30 seconds, after that reinsert the 20 amp fuse and turn the heater off with the controller. 


Alternatively, you can try to do a factory reset using the EasyStart Pro controller. This option should be the last one from the list in the Workshop mode where the codes are available.
