Hey Guys, I’m sorry for the length of this, but I am desperately in need of help. I wanted to provide as much information as possible to help troubleshoot this problem. In a nutshell, I have a two wire system Revolv/Coleman that only turns on periodically. I rent a single wide mobile home built the early 90’s. Last summer, the air conditioner failed and it was replaced with a Revolv unit. Everything worked great for about six months and then right before it started getting warm we had a couple of issues where the heat wouldn’t turn off. I’d wake up in the middle of the night as the house approached 80 when the heat was set on 72. Turning down the thermostat didn’t seem to help, so usually it took flipping the breaker to cut off the heat. That happened a couple of times, but it wasn’t the end of the world so I didn’t think too much of it. Once the A/C started getting used, I came home to a very hot house a few days. The air conditioner would run fine for a while, but then all of a sudden it just wouldn’t flip back on. The easiest way I found to fix this was to press on the furnace door. If I applied just a little pressure, the air conditioner kicked back on and worked like normal. After doing this a few times, I decided to replace the thermostat. A programmable Honeywell was already there, so I just replaced it with a newer similar model the Honeywell RTH2300B1012/A 5-2 Day Programmable Thermostat. That didn’t seem to make any difference and we continued to have issues on a month, or every few weeks. The issues seemed to get worse, so we had someone sent out who found nothing wrong and replaced two relays. After he replaced the relays things worked great for the next two weeks. Everything turned on and of like it was supposed to and life was grand. Then, out of the blue, it started all over again, except this time, pushing on the door didn’t help. The only way to trigger the a/c back on was to raise the thermostat above the current house temp, wait for the click, then lower it to the desired temp and wait for the click. It should be noted that when it turns off the words Heat Only disappear from the thermostat screen. Once I bump it back above the current temp, they reappear and then everything is fine for a while (or a few hours). The second time the tech came out, he said there was nothing wrong with the unit (since he replaced the relays) and the only solution he had was to move the delay from one minute to five minutes. This did not fix the issue. I switched back to the old thermostat which didn’t help and then I purchased another new Honeywell thermostat, this time a Honeywell TH1100DV1000 Pro-Digital 2-Wire Heat Only. Every time maintenance or the HVAC people they comment on how the other Honeywell thermostat is not what is needed for a house like mine, so I figured by replacing it with a Heat Only unit that would at least stop the comments and allow them to focus on the issue at hand. Of course, the new heat only thermostat did not fix the issue either. I’m not off work again till Friday and our rental department won’t send someone out unless I am home. I really need some guidance on what to suggest since I don’t have much faith in our tech. He seems very dismissive of the problem. The air conditioner works fine until it reaches the desired temperature. Once it turns off, there is no telling whether it will turn back on again. I appreciate any advice yall can offer me. Brandon

The filter is new, and the unit runs. Just does not produce cold air at times. Just started now. I took photos of the unit and it seems there is condensation going on the part that looks like black tape wrapped around. I know nothing about A/C units. I wanted Does this look right, or should I call someone? Should I be concerned with Freon leakage? I posted a pic of piping where leak is , and 2nd pic is of electrical. sorry the photo is sideways I don't know how to rotate A/C unit is a Rheem model RHSL HM4221JA [ATTACH]70260[/ATTACH] [ATTACH]70261[/ATTACH]
