Environmental Chamber Do You Really Need Service ??? Sometimes it seems the equipment needs servicing but in reality its a minor problem that can be corrected by the user. We at Spectrum Mechanical Services would like to offer a few checks for our customers and potential customers. 1. Make sure power is on. Sounds simple but sometimes the main power  could trip due to a power surge or spike.  2. Is the controller set properly for the desired conditions? 3. All circuit breakers in the on position? After confirming all of the above and chamber still does not operate you may need service. Feel free to contact us at 732-264-8150 to arrange for a service call.
