If the relay isn’t opening, the blower/fan can’t start. In this case, you can troubleshoot by testing the relay.To do this, you’ll bypass the relay to see if the fan will run on the direct power from the battery. If the fan functions using direct power, then you know that ...
A“conductive path” transfers the electricity from the source to the load such as a wire or circuit board. Furnace wiring diagram from Atwood Testing the RV furnace components Circuit board and relay The purpose of these tests are to ensure that power is travelingtothe circuit board and to e...
compressor motor relay winding M cannot be energized. It is also apparent that if the mode switch 80 is displaced downwardly into the "heat" position, an energizing circuit for relay winding M can be completed over the first heating stage contacts 86. The indoor fan 15 is energized by closu...
fan relay broke on the furnace logic board, ordered another board off of eBay and bypassed it to run the fan full time until the part arrived, condenser on the exhaust blower failed, just swapped the condenser and the condensate drain plugged and backed up some water into the fan housing....

The WATR SOLN terminal may also be used to activate the 24 volt relay of a humidifier installed in the system which, when connected to the PC Board, will be activated and deactivated at the same temperatures as the water solenoid valve (140°F et 120°F). Complete installation and ...

control the four-way control valve 40 and in a parallel path through normally open contacts C2-2 in series with a relay coil R3 controlling normally closed contacts C3-1 which are operable to control the motor driving fan 51. Connected between leads 78 and 76 is a relay coil R4 for ...
If not, then at step 320 when the fan delay-off is completed, the blower power relay remains energized with no break in blower power and the routine goes on to step 316. If the on-deck fan speed is different from the currently running speed at decision step 318 then the routine goes ...
