The compressor I have has one dial and that is for pounds of pressure. For my glazes, I work at about 35 to 45 lbs pressure. The sprayer I have comes from Harbor Freight that cost about $20 but Lowes Home improvement or Home Depot also has sprayers if you don't have one.
If you are looking for more of an airbrush small volume application you may need to look at Hobby lobby or other craft stores
Look at each junction from the main breaker that might be bad to the circuit box that feeds the kiln as possible failure points. The blinking power light is a valid clue as to what is wrong but no idea where. If there is a plug in 110 or 220 that could be shorting out.
