Question about Coleman (5040B750) Patio Heater
I have disassembled a large portion of the unit. I can hear the propoane coming out at the top with a slight hissing noice but the smell of propane is very slight. The propane tank is full and functional and I have cleaned out the top section where the gas is emitted. Has the regulator gone bad or is there another issue?
Most propane problems are due to a new valve on the top of the tank. It is designed to only allow a minimal flow until the line is pressured. This prevents fire flair up from broken or leaking hoses. Always turn the bottle on and wait before trying to light a burner. If the burner is on first, the propane will never come out at full flow or if you have a leak in the system, it won't pressurize sufficiently to allow full flow out of the bottle. There is never "air" in the tank.

If you're using a 20lb propane tank (Gas Grill Tank), that may be the problem. Turn off the propane tank at the tank valve and disconnect it from the tank. Wait 5 minutes and reattach the heater hose to the tank. Turn the propane tank valve on very,very slowly until it's all the way open. Try lighting your heater now. If the pilot flame height returned to normal, that was the problem.
FYI - The Thermocouple has nothing to do with the length of the pilot flame. It's a safety feature that stops the gas if the pilot flame goes out for any reason.
Hope that solves your problem. Please let me know.
