troubleshooting an issue with my gas fireplace

**Looking for some insight/suggestions to address a problem concerning my propane gas heat and glo fireplace that has a pilot light assembly with both the thermocouple and thermopile. On on the recommendation for my technician i replaced my whole pilot light assembly due to a pilot light flame and thermopile issue. My problem lies with the flame decreasing when I switch from the pilot mode to the on position. In pilot mode the pilot lights up with no problem and a very strong flame which engulfs both the thermocouple, as well as, the thermopile. As i m,ove it over to the on position the flame starts to decrease. I can move the knob slowly towards the on position enough for the main burner to engage, but if I move it over enough to fully open up the main valve, the flame no longer covers the thermocouple and/or thermopile enought to keep the millivolts needed to properly run the main valve. the reult is a clicking sound and suht off of the whole system. Also, I notice that the control valve for the main burner which regulates the flame itself has no impact on the intensity of the flame. Since it is a brand new pilot light assembly and the millivolts from thr termopile are strong, I believe the problem lie in the gas valve itself. Wall switch checks out fine and all the connections seem to be in order. Any insight would be welcomed. Thanks, Tom

was unable to check pressure due to lack of proper instrument, could it be the regulator on my propane tank is not working properly, or is it more likely a bad control valve since I am unable to increase the flame from the main control valve knob?

Obviously not right and since this is a combustion device unless you are positively 100% sure of what you are doing, I'd just have the tech fix it

summer grade one. As an example if you try to use BBQ now using propane tank filled in summer, it does not work well.

Sounds like either a problem with the gas valve not flowing sufficient gas to the pilot or an obstruction in the path between valve and pilot light.

Ayup...I thought I mentioned that earlier in the other (duplicate) thread along w/ some other possibilities but it again is pretty clear supply.
