Its specifications given by the vendor include the following: If I could pls describe what I'm seeing on my system Checked fan outside, it was not turning again. I have a 30 yr old thicknesser which uses a Leroy somer 240v single phase 2200w motor.

Check the current draw; chances are the motor is seizing. 1. So we have a failed control board; unless you're an electrical engineer with training in circuit board design and repair, I'd not attempt to repair the board.

A local technician told me it didn't matter as long as it was a higher value, but searching online I read differently; however, I cannot find an actual reason why or what actual problem will occur when exceeding this value. fuse blows at compressor start-up, we suspect a bad compressor motor. I can't guess that from a one-line e-text. Those are probably all acceptable microfarad ranges for which the capacitor can be used. Given the price, I'd rather do them both now than wait for the run-start capacitor to fail (probably next August in the "dog days"). Second, improper voltage delivery to exterior unit components forces the system to work harder as it attempts to perform its job. What is the difference between HSI and Hscei? If your motor already used a start/run capacitor, now won't start, and will run if given a spin, then yes replace the capacitor with one of same values. Therefore at this point it would be appropriate to check all of the leads and connectors to the motor and the capacitor, and if those are intact, check for a bad fan relay and if that appears to be working then it's time to pull the motor and do some diagnostic tests on the motor itself. The start capacitor may not have sufficient time to cool down after each start, and this can lead to the capacitor overheating. - detail courtesy of Bay Motor Products cited below. i kicked started the fan blades manually and the motor ran, but a little shaky. Fax: 508-995-3000 the afcap site is no longer on line , but from what I can remember the capacitor values given in their charts are for 50 Hertz applications. Are compressor capacitors difficult to replace/install? Using ..(my intuition only , I am a "Mustang Architect,and 10 year carpenter tradesman prior) capacitor. But opting out of some of these cookies may affect your browsing experience. Check or clean your air filter. It depends on the voltage requirements and ampacity of the motor it's starting or running; see the motor data tag. Capacitor Voltage Rating Selection Limits It helps to add solder to the joint too.
