Emglo Compressor No Start....

| Jeff Sellers 2005-06-17, 11:34 pm |
| Hey Group,
I've got a small Emglo compressor (AM39) that suddenly stopped starting
today. It humms for about 5 seconds before tripping it's internal breaker.
I'm thinking bad motor start capacitor.
Is there a way to test the capacitor...like with a multimeter ????
Thanks
Jeff

| yes remove the leads from the capacitor, short the terminals to drain any
charge, set the meter to a low ohms setting now check that the capacitor
conducts then opens . This is better done with a analog meter because they
usually pass more current on ohms checks but digitals can be used. The
capacitor should not continue to conduct continuously nor fail to conduct.
If repeating the test short the terminals of the capacitor between each
test. You may need to adjust your ohms settings to get the easiest to see
results. The theory is that a capacitor is a energy storage device that
charges then discharges when more the voltage drops.

| Thanks Jeff,
I already replaced the capacitor....Everything else seemed OK so by process
of elimination....
Runs like a champ now !!
I will save your test info for future use, though !!!!

| Jeffery, thank you for your response to Jeff's query. I have always
wondered how to test conductors without a $300 meter.
