Customer Question
We have an E7...

We have an E7 error and was told it was a connection problem and we just had to turn it off from the unit but we can't seem to locate the on/off switch. Do you know where it is?

Contractor's Assistant: How old is the appliance? Have you gotten error messages before?

3 years

Contractor's Assistant: Do you plan on doing the work yourself?

If it was just to turn it on and off, but if it needs more we will have a professional come out. We bought it from a A1 in Meridian

Contractor's Assistant: Anything else we should know to help you best?

No. the main unit is working fine. It is a 2-ton system with three wall units. it's the two bedroom ones that are getting the E7 error

It's at our rental I'll have to get the paperwork it'll take me a few minutes
HVAC Technician: Phil, Mechanical Engineer replied 6 months ago

Thanks, ***** ***** brand and model number off of a tag on the unit itself if you cannot find the paper work... if there is a wiring diagram that shows the gas valve and blower wiring, take a close up, well focused photo of it and attach it here using the 'add files' link and I will mark it up with trouble shooting instructions.

The technician from A1 said it was a connection error and we just had to turn the units off for a couple of minutes and then turn them back on. He said their was an on/off button on the units but we're not sure where they are.

I am not at the rental at this moment. If you need a picture I cannot get there tonight. Could I just turn the system off at the breaker and flip it back on in a couple of minutes?It has its own circuit
Customer reply replied 6 months ago
Are you still there?
Customer reply replied 6 months ago
I am assuming that you are not there anymore. That was an expensive no answer.
