If your PTAC Direct DCP073A25AA electric heat unit isn't starting, here's a troubleshooting guide.
Possible reasons for the unit not starting:
- The unit might not be plugged in properly.
- A fuse could be blown.
- The circuit breaker may have tripped.
- The unit may be turned off.

Here's how to troubleshoot:
