Well Gunrunnerjohn and cjack (not sure if he can see this reply?)
I tested the signal level after the foam insulation was on the base for 10 minutes.
The signal was near zero, less than 100mVdc
I removed the foam and waited a few minutes and the signal came up to 1.8VDC.
Then I noticed that if I press lightly on the base in the center where the remote goes the signal goes to zero again.
So now we suspect heating as a primary driver of the cause. And the and root cause is most likely a PCB cold solder joint of crack land run.
Strange, just last week I had our double wall oven controller/relay board out because the ovens were acting flaky.
Turns out there were cracked joints on the single sided PCB ate connector headers.
I will open the base up and find the culprit and report back.
I cant believe how helpful you guys are.
I hope that I will be able to help others in the future.
@cjack posted:There is also mechanical jiggling the base that can cause an intermittent connection to make and break. The bottom line though is low base signal from whatever cause.
Hi Cjack
You were spot on.
The heating in the base is opening up the signal path output.
Then confirmed its a mechanical break issue, most likely pcb cold solder or broken/cracked joint.
Thank You!!!
