I had to temporarily remove one of the truss bracing boards to be able to replace the blower motor. With the blower assembly out of the unit I still had to remove and replace the motor in the attic. I replaced the variable speed blower motor from Water Furnace and retained the faulty one to return to WF. I wired everything back together including the pan switch and checked blower motor operation. I secured the truss brace and made sure it was more secure than before it was removed. I did use wood screws so that if it ever needs to be removed again it will be much easier. Unit operates normal.

On arrival set unit to call for cooling.found system has a leak .unit is 15 years old with r22 system .customer is getting an estimate to replace tomorrow.unit is not operating at this time . Warrantied per Darlene
Upstairs unit not operating outside because the voltage absorption system was open for the compressor. I replaced it with 40&5 uf dual run cap and tested the unit. Unit uses r22 refrigerant and the pressures were lower than normal. I went into the attic and had 87 return and 69 supply air temperature. I opened up the blower compartment and felt refrigerant oil inside of the evaporator drain pan. I spoke with the customer about this because it is cooling but most certainly has a leak in the coil. I had to make an estimate to replace the coil and document what I found to protect myself. Otherwise the unit is operating normal.
