Hi:

The fridge in my 91 westy is not lighting on propane.  Do I need to
replace the electronic ignitor?

The fridge:  this is the stock 90-91 style Dometic 182B EGI with auto
electronic ignition.

The symptoms:  When I try to light it, the little red display at upper
right glows briefly, then goes out.  In other words, the red light
doesn't flash, and I don't hear the normal clicking sound.  I think
its not sparking.

The fridge works on DC.  After plugging it in with 60-70 temps
outside, I get cooling that is possibly ok but maybe slow:
start     84 deg F
2 hr     60
4 hr     51
20 hr     38

Do you think I need to replace the ignitor ($172)?  What about the
"spark plug with cable"?  thermocouple?

And does it seem to be cooling with DC reasonably well?

Thanks,
Bill
