Sorry guys never got to it, just let the repair man do the work. Plus I started to get sick from the virus going around. Today repair guy came and found a bad inducer motor. Parts were free from my warrantee since the unit was only 2.75 yrs old. They were the ones that installed it so they had it in stock. Took about 45 min to install. I just paid for labor for $189. Kind of high I'm thinking but can't complain about getting heat.
