Mini split starts up after time delay and runs for only a few seconds before shutting down with a 5 flash at indoor unit. 5 flash according to mylinkdrive troubleshooting refers to outdoor power system. Indoor unit manual reports that condition causes compressor to stop for overcurrent protection or start up failure protection. As tech saw outdoor unit shut down, tech gets a 2 red flash at outdoor unit control board. Tech also found a wire rub on the white wire leading to compressor. Tech repaired wire rub with wire nut. Compressor ohms fine with fieldpiece meter, but pressure tap pressure does not change when outdoor fan starts. Compressor is not starting. Tech got DC line voltage on white and red lead on one occasion. Tech got no voltage on each subsequent try. Tech suspects faulty outdoor unit control board due to wire rub. Tech recommends ordering outdoor unit board and also installing a surge protector. Outdoor unit serial number is correct in ServiceTitan (last four are 2875). C
Replace 2.5 Ton Package Heat Pump With New Mitsubishi 2.5 Ton Mini Split Heat Pump With WiFi Programmable Thermostat
Pre smoked 10 ton unit and it passed. 10 ton, unit 427, unit 429, and unit for bathrooms all passed electrical and mechanical inspection. Sealed up line set penetration on roof for 10 ton unit per inspectors recommendation. Sent pic to inspector after sealing.
Inspector noted more needs done. Smaller gauge for pressure test, gas lines need repainted for better coverage, audible and visual alarms needs wired in for duct detector, door needs put on split system for filter access. Gas line inside is good with the stickers I put on.
Tech changed out Symbio board on new Trane gas pack and system still had same issues. After speaking with office we will return to further inspect. Tech installed original Symbio board back on system.
On arrival no power to system. WEC here and got corrected…..fuse blown in main panel. Cannot get system to turn on. Surge that hit fuse may have damaged something in system. Need to return with duct detector and symbio app to further diagnose.
Unit 2.1… checked wiring at air handler, condenser, and detector. All look correct. Could not pre test due to kids napping and no alert was sent to teachers. Need to return one morning to smoke test. Unit 427 is for room 427. Changed air handler fuses to 45 from 60. Changed fuses at condenser from 30 to 25. Unit for bathroom got pictures of air handler, condenser, and stat.
Package HP 5 - Right Side of store - upon arrival, blower door was off of the system. Tech replaced door for testing. technician found all electrical testing within spec. However, when checking the cooling, the technician found that the delta t was not sufficient. Temperature changeover was only about 11-12 degrees. Tech swept the indoor and outdoor coils with leak detector but the search came up negative. Previous notes on this system have stated there are some refrigerant challenges and this system has already been turned over to field supervisors office. System is capable of heating with assistance from heat strips. Package HP 4 - Middle of Store - appears to be new system installed in early 2024. No challenges found during today’s visit. System cleaned and inspected. System cooling and heating properly. Delta t on both heat and cool are between 19-22 degrees. Electric heat also tested and works to spec. Package HP 3 - Left Side of Store - upon arrival, tech found the system call
tech returned to replace auxiliary drain pan. Also, tenant noted water spots on ceiling. After investigation the tech discovered water was penetrating the roof and leaking onto ceiling. (Pictures provided).
Techs replaced ther wire system is operating properly at this time.
Tech replaced constant torque blower and found normal operation. Customer also requested diagnosing school room 314 mini split. Tech added commercial service call fee. Tech found system running AC with a heat call. Mini split is ran off a Vision Pro connected to an adapter. Adapter has no O wire going to it therefore it cannot differentiate between a heat and cool call. Tech re wired and reprogrammed thermostat for a conventional system and found system running heat and AC modes. Adapter recognizes y for cool and w for heat and system runs accordingly. Tech also verified the heat pump runs in heat mode with a W call.
