If you have a Pipe Organ, you may need to check the maintenance arrangements for your instrument.
If your church has an organ, who lubricates the blower motor? Are you sure? A number of churches who thought that the organ tuners were responsible for blower maintenance have found out the hard way that the tuners thought it was the responsibility of someone else. Repairing or replacing a burnt-out motor is very expensive: do please check that your blower motor is properly maintained!
