After three years of flawless operation, my MTH Fire House has ceased to function properly. Before I take it in for repair, I wondered if any on here had some advice on what could be wrong. The problem began when the power was turned off mid-cycle. Normally, that results in the truck returning quietly to the house. It did, but door didn't close fully. Then, no response to button, but then, all of a sudden, any power brings truck out without sounds and it seems to keep trying to run, with gear noise. All I can think is that there has been some type of electronics control chip failure, but I really don't understand its workings. Removing the bottom plate only showed a large, geared wheel with two switches.
Any thoughts or advice? There is an approved MTH Repair LHC in the area, and I am also reasonable driving distance to MTH HQ in Columbia, MD. I note that they have "walk in service" some mornings.
Thanks for any thoughts.
