Installed new gmv95 unit will not do anything !
1. red led on
When powering up red led is supposed to flash once and stay on ,but it doesn't flash once it just comes on right away.
2. doesn't flash any codes
3. jumer are to w or are to g nothing happens
4 I reversed polaririty to see if it would throw a code it did not
5 green led is dim , really dim and flashes really fast, fast enough where I cannot count the flashes
6 checked polarirty and ground both fine
7 checke limits and saftys all okay
8. checked all wiring and plugs all were tight wiring matched wiring diagram
9 checked all dip switches okay

So can any one chime in on this goodman furnace ,is the main board defective from factory or am I missing something here. This furnace has never ran :confused:
