I need a hand finding the correct condenser motor for an old copeland brand 5hp condensing unit. Missing model plate, it uses a mra2-050a-tfc compressor w/ a 6 blade 24", 27 deg. pitch fan. It currently has a 1075 rpm motor pullling 5.3 amps (3/4hp). Motor is only rated for 4.4 amps. I believe this unit started out w/ lower rpm motor. Sorry no pic but this unit uses twin receivers under the compessor. Please let me know what I need to fix this. Thanks
