At Wolff Mechanical Inc. we provide quality air conditioning service and repair. In order to keep your air conditioner running smoothly, it is important to check all aspects of the unit. The thermostat is the control system inside of the home that helps to turn the system on and off. If this part of the unit is not working properly we would be happy to help you fix the problem. Here is the some information on how you could possible resolve the issue with your thermostat yourself.

Thermostat

The thermostat is located behind the control panel. Here’s how to test and/or replace the thermostat:

Step 1: Remove grille and control panel from unit. Thermostat has special sensing bulb attached to it; this part extends from thermostat into evaporator coil area. Its role is to sense temperature, which is controlled by thermostat.

Step 2: Remove thermostat carefully because you must return sensing bulb to identical spot later. To make replacement easier, tag location of bulb before you remove thermostat.

Step 3: Check thermostat with VOM set to RX1 scale. Clip probes of tester to thermostat terminals, and turn temperature control dial to coldest setting. If meter reads zero, thermostat is functioning properly. If reading is higher than zero, replace thermostat with new one of same type. If thermostat is held to control panel or frame with screws, clips, or metal tabs, connect new thermostat the same way the old one was connected.

Note: If the thermostat has more than two lead wires connected to it (not counting the sensing bulb wire) do not try to test or replace it. Instead, call a professional service person.
