Paulabrian Report post Posted September 22, 2023 The thermostat in our 2019 keystone cougar is reading 55 degrees, so the AC won’t run. Anyone experience this? We just arrived at beautiful Topsail in Florida- and AC is a must! Share this post Link to post Share on other sites
wildebill308 Report post Posted September 22, 2023 With no outher information I would say try this. Turn the thermostat off. Pull the cover off and see if it has a fuse in side. Cheack the fuse. Make shure all connections are tight/clean. This includes any grounds. Re assemble and see if it works. Bill Share this post Link to post Share on other sites
rayin Report post Posted September 23, 2023 Yes, without details we must guess instead of share knowledge and experience. Please provide brand and model of A/C, and same for thermostat. Some thermostats can be reset by disconnecting from all power for at least 30 minutes, which is enough time to check the fuse and have a cold beverage. Being near the ocean helps with lower humidity, but temps are still about the same, enjoy. Share this post Link to post Share on other sites
