I have had that happen before on my Brother 1500..went to the local repair store---a Viking dealer also---and he told me it would be fine without it---??? NOT...so I asked that he order me one--he said fine----never heard from them again--I called the Brother dealer that is 75 miles away...ordered 2....one for a backup--it was here in 2 days!! My husband put it
in for me and it has been fine ever since---needless I will never go back to the local repair shop---
