3400A816 Heating Element Issue
Posted: Mon Jan 28, 2008 8:28 pm
Hello Everyone.
This is my first post although I come here often and have found your site very helpful, SO Thanks
My Problems is simple I think, I have a 3400a816 that up until recently was working great. When running heat mode this thing usually runs you out of the trailer from the intense heat that it puts out. All of a sudden its very hard to keep it over 50 deg. when the outside temp is under freezing.
I checked the unit, Heatpump side of things working fine, the electric grids are not firing up (they are set up as 2nd stage, emergency). SOmeone had cut the breaker to the outside condensing unit and the electric was all that was heating for an unknown amount of time so I know they were working fine.
THis is what I have checked.
I first checked Bus Fuses with DVOM, All Good
I then pulled the panels and cut power and ohm'd the coils on the right side as well as the left side. I first checked resistance between the top and center posts (no cont, open circut) I then checked between the center and lower posts (no continuity, open circut) I checked between the top and bottom posts as well just for good measure as I dont have wiring diag so not sure of wiring config of elements and got the same result.
I checked the other sides elements in the same fashion and got the same result. I have open circuts across all posts of the heating elements. By this it is from my experiance that the elements are burnt out?? Am I correct on this?? I didnt check the input voltages as I didnt see the need if I had verified the elements were open.
Now from what I read in other posts in the forums the heating elements are no longer available for this unit. and I need to get restringing kit from the electrical section?? If my diag is correct my question is you offer 3 different kits. this furnace is stamped a 54k BTU. Which kit the 5kw, 3kw?? and how many do I need to restring all of the heating elements??
Should I replace the senquincer?? I know this thing ran for approx a month of continous running on just the electric grids so I am sure they were heated up a good bit.. Thought for the money would it be smart to go ahead and replace it? THis thing has been butchered up by someone in the past so it has been difficult figuring out the info, especially without the electrical diag's But I think I got the basics down. I have installed Heat pumps and done alot of furnace repairs but this one I am just not sure about.. HELP PLEase
I am also wanting to make sure before buying a wiring diag from you. On this unit I really need to know the t-stat panel diag as I cannot see anything on the panel and whoever wired it didnt use normal color codes for the wiring. Will this wiring be included in the wiring diag that you send for the $15 ??
I need to order fast so as soon as you let me know I will get the parts ordered. Its Cold Here on the east coast... :=)
Sincerely
