Ok, this one has me baffled. I have owned a Honda Eu2000I generator for a few years now. I have used this generator for camping and as a back up for around the house too. During the winter when we have power failures I've always been able to run our old (gas)furnace, fridge and a couple lights with no problems. Last year we upgraded our furnace to a new Trane high efficiency model. It has an electronic ignition and a computer control board in it. Well I just learned today (during a 4 hour blackout) that our new furnace wont ignite when plugged into the generator. The vent motor kicks on, then igniter tries to light but doesn't. Then vent blower turns off. Then the main blower turns on and blows cold air. The furnace shows an error code and that says "check igniter" During all of this the generator shows no signs of a large load.
Things that I researched and have tried with no success...
I changed the polarity...still faulted
I bought and installed an eight foot ground rod with 6 gauge copper ground wire into the ground and connected it to the generator....still faulted
I connected a ground from the house wiring directly into the furnace while plugged into the generator...still faulted
But as soon as I plug it into the house current (after power is restored) she works like a champ!!! Generator....no go!!
I just don't understand why when its plugged into the generator it wont ignite, but plugged into the wall its just fine. Other replies that i have read online is dirty power or uneven voltage. Well their fix for that was to use a nice inverter style generator like the Hondas or yamahas, but that is exactly what I'm using. I'm pretty bummed that we have no more back up for our winter power outages which unfortunately happen often in our area. If anyone with any experience with this that might have any ideas that I'm not getting, I would greatly appreciate your input.
