When picking replacement parts for your furnace, cost should not be as critical as most companies make it. The cost of heating elements between a good manufacturer and a bad one is negotiable, as compared to the overall financial investment. The production time and quality of the parts acquired by picking a respectable manufacturer will more than make up the difference. Remembering the following pointers when picking a manufacturer will guarantee less downtime due to a defective item.
Manifold Heater and Cartridge Heater.
Cartridge heaters are utilized around the flow channel to guarantee uniform temperature levels. It is important to keep the distance between the heaters and the manifold equal or greater than 1x the diameter of the heating element.
Thermocouple placement should be located equally distanced between the heating element and the flow channel, and should be set deep to guarantee an accurate reading.
If an internal thermocouple is utilized, it is important to ensure that it is located towards the center of the heating element, depending upon whether the controller is grounded or ungrounded.
A few of the most typical reasons for failure consist of:
Lead short out.
This can be fixed by changing the lead type. If fiberglass leads were utilized, this might be the source. Hot runners by nature create gases, which in time, saturate the fiberglass material, causing it to short out between the leads. Depending on the ambient temperature around the lead area, Teflon leads can be utilized to correct this, as they are more resistant to gases Plano Air .
Internal thermocouple not reading correctly.
This can be caused by 2 different reasons. One reason is the thermocouple has to be located in the center of the heating element. If not, you will never obtain a correct temperature of the flow channel. The other reason is whether or not the unit is grounded or ungrounded. Consult your controller manufacturer to determine this.
