Multiquip 29504 Thermal Switch 230 F

The Multiquip 29504 Thermal Switch 230 F is a genuine OEM component designed for HTX44K4 and HTX44K5 hydrostatic ride-on power trowels. As a direct factory replacement, this switch is built to the same specification as the original part and installs in place of the existing unit without modification. Sourced directly through authorized distribution, the Multiquip 29504 ensures your machine is back to spec quickly and correctly.

Key Features

• Factory-Spec Trip Point — Rated at exactly 230°F, matching the original thermal cutoff threshold to protect the machine's engine and hydraulic systems from heat damage.
• Genuine OEM Construction — Manufactured to Multiquip's original specifications, ensuring consistent switching behavior and long service life under continuous trowel operation.
• Direct Drop-In Replacement — Designed to match the original mounting configuration and electrical connection on HTX44K4 and HTX44K5 trowels for a straightforward swap.
• Confirmed Fitment — Verified for use on HTX44K4 and HTX44K5 hydrostatic ride-on power trowels.
• Critical Overheat Protection — A failed or out-of-spec thermal switch can allow dangerous temperature buildup or cause nuisance shutdowns; an accurate replacement keeps the machine running within safe operating limits.

A thermal switch is a temperature-activated safety device that monitors heat levels within the machine and triggers a circuit open or closed when a set temperature threshold is reached — in this case, 230°F. On hydrostatic ride-on trowels like the HTX44K4 and HTX44K5, it plays a key role in protecting the engine or hydraulic system from overheating damage during sustained finishing work. When the switch fails or drifts out of calibration, the machine may shut down prematurely under normal load, or worse, fail to shut down when it should — making timely replacement essential for both uptime and equipment longevity.
