All of a sudden my bedroom blind over the emergency door won't budge. You can manually crank it up and down by twisting the two sides but it is a slow process. Anyone else have this issue and have ideas on how to fix?
Sounds like the spring just slipped/reset (happens to mine on occation). If you hold the roller while cranking the left knob (clockwise), it should re-wind the spring (it will take many revolutions). This should fix it for you.
+1 on the FANTASTIC service by MCD. They will go out of their way for their customers.
