have a dometic 1402 , getting error code 11 which reflects problem with heating element in freezer,,, so replaced the element , checked all fuses and all connections.. The unit works fine, i.e freezer and fresh food compartment. everything works,,, but cannot make the error code go away... someone says only dometic tech can make it reset. does anyone have any suggestions to reset this?

You pulled and checked the dedicated fuse? 7.5 amp? Doug

Error codes (of course) are generated on a chip/cpu level. Removing power from these goes to default (unless computer is backed up by battery which on dometic it is not). As others have said try the shutoff method. Also check all of your wires leading to the control board for proper connection. Doug gave some great insight on other possibilities. I've had so much trouble with RV fridges that I only go with real fridges / dorm fridges in my coaches.
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.
What Doug said- error 11 simply senses no continuity (or power, if fuse is blown) on the defrost heater circuit. Could be bad connection, bad ground or blown fuse. As soon as it is corrected, the error should go away- no real reset needed, other than off and on.
1. The most common code is ER13. I have replaced at least 2 dozen drain defroster foil tapes and EVERY TIME, once the bad part is replaced the code goes away. No reset ever needed 2. Did you replace the 120 element at the back side rear? If so, That is NOT the defective part that Error code 11 refers too. 3. If you replaced the correct freezer defrosting element and the code did not go away, either the new part is defective or you did not install it correctly. 4. Is this the P/N you used? 3850675012 A Heating Element, Cooling Flange, Frzr. 5. DOUBLECHECK fuse F4 (7.5 amp) Doug
Like Biscuit said above....try turning it off first... But, as I understand it, error codes are stored in the board and will not clear until ALL power is disconnected.
