RE: How cold should the air conditioning get the RV?

One key point is; AC units need to cycle. That's why in a couple places we camped this summer, we had to raise the inside temp to 75 instead of 73 a couple days. Why?

RE: Need a 1/2" Propane Hose ASAP

Home Depot sells flexible gas line by the foot, or 50-100' rolls. They have all the parts you might need too. That gas line is only under 7 pounds of pressure. Are you referring to csst (corrugated stainless steel tubing)? If so, be sure to verify that rv use is allowed by the manufacturer.

RE: Furnace Short-Cycling

Regarding that restrictor inside the exhaust vent tube, which decreases the inside dimension of the tube to about 1/2" diameter, do you know it's purpose? When it's removed, no more short-cycling. Can I just remove that restrictor permanently? It sure seems like you have narrowed the problem to combustion ventilation. Sounds like the flame is smothering itself. One other thing to check is that that draft inducer blower wheel is secure on the motor shaft. As you may know by now, the draft inducer and air circulation blower share the same motor. As far as removing the restrictor, due to liability issues, you may want to contact the manufacturer.

RE: Dometic AC unit

A thermocouple is a device which generates electricity when subjected to a flame, most often from a pilot light.It is unlikely to be found on an rv air conditioner. The device mentioned in previous posts would likely be a thermister, which is a resistor whose resistance varies with the temperature it is subjected to. This may be found lodged into the evaporator coil of the air conditioner. Its purpose is to turn off the compressor when the condensation on the evaporator begins to freeze.

RE: Suburban SW6 lights but drops out after 30+ seconds

Verify the integrity of the vent system. Re-circulation of exhaust gas into combustion air may cause similar symptoms.

RE: Neat little fresh water in an ABS pipe idea

Don’t forget guys. A 4” pipe is the outside diameter! I would say around 3 gallons? I seldom venture south of the border, but up here in God's country, the nominal size of pipe refers to the inside diameter. https://pvcfittingsdirect.com/pvc-pipe-sizes-chart/

RE: What do you do for condensation inside cabinets?

Closed cabinet doors insulate the cabinet space from the living space causing it to be cooler. Air at 100% relative humidity and 50° temperature will have 55 grains moisture per pound of air, If you increase the temperature of that air to 70°, the relative humidity drops to 49%. At 80°, the relative humidity will be 35%.

RE: The kid meets the furnace thermostat...

The heat anticipator controls the length of time the furnace operates per cycle. It should be adjusted to the furnace control (milli)ampere setting listed on the furnace or measured thru the stat wires. I am confused by the phrase "2 wire no electricity system". What is the purpose of the wires, if not to conduct electricity? Snap action and bi-metal depend on flexing of metal due to temp changes, to open and close the stat contacts. The magnet inhibits contact chatter. The advantages of many digital stats are not insignificant. Easy to read lighted digital display Adjustable cycle rate Adjustable min/max temp settings Low stat battery freeze protection These features may be not available on all digital stats.

RE: black plastic waste pipe

Home Depot sells "Socket Saver" 3" for $13.22 Menards sells "Saver Reamer" 3" for $8.99 Just in case you need one.

RE: Modifying roof a/c cover

I would have liked to see the youtube guy measure the average flow thru the condenser with the cover off and again with the cover on before he modified the cover and again after the modification. I suspect the airflow improvement would be less spectacular.
