Troubleshooting advice requested, because the LED blinking
constantly supposedly indicates that the heater is wired
in reverse (which really isn't very likely, so I must be
misinterpreting something obvious).
Heater worked last year (
AFAIK).
It just started getting cold in California, so, the heater power
was turned on, and ... and ... and ... uh ... um ... no heat.

Thermostat batteries are good:

Heater power is on and the blower blows but the red led blinks
at a steady pace forever.

Checked that the switches inside were all on:

Checked that the fuse on the circuit board was good:

The sticker says constant flashes indicates reverse wiring:

But, there's no way the wiring was changed between last year & now.

Here's what it looks like inside:

I don't know where the model number is, so, I don't have a manual
yet.
Debugging suggestions are requested, and very helpful. Thanks!
